This was CNBC's live blog tracking developments in the Israel-Hamas war. Click here for the latest Israel news and updates on Gaza.

Residents of north Gaza have begun to flee south of the Wadi Gaza river, after an evacuation call from Israeli military. Palestinian militant group Hamas has rejected the order, as concerns mount over the possibility of an Israeli incursion into the Gaza Strip.

Israel has given the roughly 1.1 million residents of north Gaza about 24 hours to leave before a deadline near midnight local time, the United Nations said. The Israel Defense Forces, who has yet to confirm plans for a ground offensive, only says the evacuation should be carried out as soon as possible. Israeli military has amassed troops at the border with Gaza over the course of the week and cites its main objective remains stripping away the military capabilities of Hamas.

Human rights agencies have decried the evacuation, which threatens to compound the existing humanitarian crisis in Gaza.

The Gaza Strip remains under total siege after Israel cut off supplies of food, fuel, water and electricity to the area following a bloody multipronged Hamas attack over the weekend. The death toll since the offensive and Israel's retaliatory strikes has continued to mount.

Palestinians evacuate from northern Gaza

Entire families could be seen fleeing northern Gaza in cars, trucks, donkey carts and on foot after the Israeli military asked 1.1 million people to evacuate ahead of an expected ground invasion.

The United Nations has demanded that "Israel immediately rescind its order for 1.1 million Palestinians to leave northern Gaza within 24 hours, condemning the evacuation order as a crime against humanity and a blatant violation of international humanitarian law."

"Forcible population transfers constitute a crime against humanity, and collective punishment is prohibited under international humanitarian law," said Paula Gaviria Betancur, special rapporteur on the human rights of internally displaced persons. "We are horrified at the prospect of an additional 1 million Palestinians joining the over 423,000 people already forcibly driven from their homes by the violence over the past week."

Israel has not yet said anything about the timing of the invasion.

Three convoys of evacuees in Gaza were hit by strikes, killing 70 people, according to a statement released by Hamas. NCB News reported.

At least 1,300 people have been killed in Israel and 1,900 people have been killed in Gaza as a result of the Israel-Hamas war, according to official estimates from both sides.

'There is nowhere to hide from the bombs': Civilians trapped in Gaza can't escape Israel's siege

In the Gaza Strip, a small stretch of land blockaded off with concrete walls and barbed wire fences and whose last remaining border crossings have been shut, survival is increasingly a game of chance.

"It's insane and brutal — I can't believe they're doing this to the whole population. The amount of airstrikes are massive," Omar, a Gazan development worker with two young children, told CNBC via voice note. "We're OK for now but it's very scary, and with each bomb, we feel it's going to be our turn." Omar asked that only his first name be used out of concern for his family.

Without bomb shelters, people try to hide in hallways, away from windows, in schools, or even in the street alongside piles of rubble. But those spots aren't safe either, Palestinians in Gaza say.

U.S. airlines add flights from Athens to get citizens out of Israel

Major U.S. airlines on Friday said they were adding flights from Athens to help travelers trying to return to the U.S. after they and other carriers ceased service following the violence that broke out last week.

The State Department said it would begin chartering flights to help "U.S. citizens and their immediate family members" fly to the U.S.

Delta Air Lines said it was adding three flights from Athens early next week on an Airbus A330-900 to New York. United said it has added five roundtrips between Athens and its Newark, New Jersey, hub, with capped fares, on a Boeing 787-10.

"We're in close touch with the U.S. State Department as it seeks to add additional options for Americans traveling from the region," United said.

American Airlines upgauged aircraft to Boeing 777-200s and 777-300s, it's largest planes from Athens to New York, over the weekend and early next week. Most foreign airlines have suspended flights to and from Israel, or scaled back service, while Israeli airline El Al is still flying.

Biden: Need to 'urgently address the humanitarian crisis in Gaza' is a priority

President Joe Biden said the need to "urgently address the humanitarian crisis in Gaza" is one of the priorities of his administration, a notable statement at a time when tensions and emotions are running high in Israel and Gaza.

"At my direction, our teams are working in the region, including communicating directly with the governments of Israel, Egypt, Jordan and other Arab nations and the United Nations to surge support and humanitarian resources" to Gaza, Biden said at an event in Philadelphia.

"We can't lose sight of the fact that the overwhelming majority of Palestinians had nothing to do with Hamas and Hamas' appalling attacks," he added. "And they're suffering as a result, as well."

U.N. chief calls for 'immediate humanitarian access' to Gaza

United Nations Secretary-General António Guterres called on all parties to allow "immediate humanitarian access" as the Israel-Hamas conflict intensifies.

"We need immediate humanitarian access throughout Gaza, so that we can get fuel, food and water to everyone in need," Guterres told reporters at the United Nations in New York.

Guterres described the Gaza Strip, which is under intense bombardment, as a densely populated warzone "with no food, water or accommodation."

"Hospitals in the south of Gaza are already at capacity and will not be able to accept thousands of new patients from the north," Guterres said, adding that the health system is "on the brink of collapse" and "morgues are overflowing."

"Even wars have rules," he said.

Netanyahu: Hamas has only 'started paying the price'

Israeli Prime Minister Benjamin Netanyahu issued a new warning to militant organization Hamas, saying his country's response to the ongoing terror attacks has just begun.

"We have no choice but to fight," Netanyahu said. "We know what we're fighting for and for whom."

"We're hitting our enemy with unprecedented force," he later added. "Our enemies have only started paying the price. This is only the beginning."

The statement comes as 70 people were killed Friday when air strikes hit three convoys of evacuees as they tried to reach the southern Gaza Valley, NBC News reported. Most of the victims were women and children.

More than 200 evacuees were also injured in the attack.

Blinken thanked Qatar for assistance with hostage release

Secretary of State Antony Blinken thanked Qatar officials for their help in assisting with the release of hostages held by Hamas.

"Our key focus for us necessarily, ideally, the United States is sharing with us, is how to put an end to this conflict, how to deescalate, how to get a humanitarian corridor and how to get the hostages back safe," Blinken said during a press conference with Prime Minister of Qatar Mohammed bin Abdulrahman bin Jassim Al Thani.

"I really thank Qatar for the work they're doing trying to help secure the release of hostages. This is something we deeply appreciate, I know that other countries do as well. And it's something that, I've also been making clear in all of my conversations on this trip, that there can be no more business as usual with Hamas," Blinken added.

'This is only the beginning' Netanyahu says, vowing to use 'unprecedented force'

Israeli Prime Minister Benjamin Netanyahu said his country's enemies "have only started paying the price" for the attacks of the past week by Hamas militants that have devolved into a bloody war.

"We'll never forget the atrocities that have been done to us and we'll never forgive," Netanyahu said in a live address. "This is only the beginning."

"We're hitting our enemy with unprecedented force," he added.

The prime minister did not detail the next steps of the anticipated ground invasion of Gaza.

Israel military says it has carried out small raids into Gaza strip

The Israeli military says for the first time that ground troops have been operating inside the Gaza Strip.

In a statement Friday, the army said troops had entered Gaza to battle militants, destroy weapons and search for evidence about the missing hostages held by Hamas.

The announcement did not appear to be the beginning of an expected ground invasion of Gaza. Israel has been massing troops along the Gaza border since last Saturday's deadly incursion by Hamas militants.

Billionaire Haim Saban will launch a campaign to help Israel next week

Billionaire media mogul Haim Saban plans to launch a campaign in the coming days to help Israel as it fights a war with Hamas.

"Since the barbaric Hamas started their onslaught on man women and children, we have spent the week developing a comprehensive campaign, which we will announce top of next week," Saban said in an email to CNBC. He did not provide further details.

With an estimated net worth of $3 billion, Saban has financial resources that could provide significant aid to Israel, where he has personal ties. Born in Egypt to Jewish parents, Saban's family later moved to Tel Aviv, according to Forbes.

Since the early 2000s, Saban has donated more than $30 million to Democratic political campaigns and supportive groups. He also funded a major Middle East research program at the prestigious Brookings Institution.

First charter flight to evacuate U.S. citizens from Israel has departed

The first charter flight organized by the State Department to evacuate U.S. citizens and their families from Israel is airborne and en route to Europe, the White House confirmed.

Reuters reported that the charter flight landed in Greece.

"The president has asked his team to ensure that we are assisting U.S. citizens who want to leave Israel and providing them with a safe measure a way to do that. So again, we're arranging these charter flights to assist the U.S. citizens and their immediate family members who have been unable to book commercial tickets," Kirby said.

Israel's Gallant: Gaza war is existential, Hamas part of Iranian 'axis'

Israel is waging all-out war on Hamas militants to effect permanent change and safeguard its future as a prosperous democracy, Defense Minister Yoav Gallant said on Friday, describing the faction as part of an "axis of evil" with Iran.

Asked during a news conference with his U.S. counterpart Lloyd Austin whether Tehran consented to the weekend Hamas onslaught from the Gaza Strip, Gallant said: "It doesn't matter ... (because) the idea is an Iranian idea."

'Tall order' to carry out the evacuation of Gaza City, Kirby says

A full-scale southward evacuation of the roughly 1.1 million people in Gaza City, in line with Israeli military guidance, will be a "tall order," according to John Kirby, National Security Council coordinator for strategic communications at the White House.

"That's going to be a tall order, given how densely populated it is, given that it's a scene of combat. There are bombs falling, and strikes happening. That is a lot of people to move in a very short period of time. We recognize the challenge there," he said Friday in a MSNBC TV interview.

Israel instructed the residents of north Gaza to move south of the Wadi Gaza wetlands overnight, citing their own safety. Concerns are bolstering over the possibility of an imminent Israeli ground incursion into Gaza, following the terrorist attacks of Palestinian militant group Hamas last weekend. The Israel Defense Forces have since sealed off the Gaza Strip and say their only objective is to remove the military abilities of Hamas.

"We understand what they're trying to do and why they're trying to do this. They're trying to isolate the civilian population from Hamas, which is their real target," Kirby said.

Human rights groups have criticized Israel over the evacuation order. The U.N. has said the IDF informed it that Gaza City residents must flee within 24 hours. The IDF says the evacuation must happen "as soon as possible."

"We also want to see that there are opportunities [for] safe passage out of Gaza writ large, that people have the ability to leave Gaza, and that's not the case right now, so we're continuing to work with the Israelis and the Egyptians on that as well," Kirby signaled.

The U.S. earlier this week noted it was in talks with Egypt — the single land neighbor of the Gaza Strip other than Israel — to organize a humanitarian corridor. A route for the safe passage of refugees has yet to be declared.

Biden expected to speak to the families of Americans held hostage by Hamas

President Joe Biden is expected to speak to the families of Americans held hostage by Hamas, a White House official confirmed to NBC News.

"I think they have to know that the president of the United States of America cares deeply about them, deeply. We have to communicate to the world this is critical," Biden said in a "60 Minutes" interview clip aired on CBS "This Morning" show.

"This is not even human behavior, it's pure barbarism and we're going to do everything in our power to get them home, if we can find them," Biden added.

The White House has previously said "less than a handful" of U.S. citizens are believed to be held hostage by Hamas.

How Israel's tech community is responding to war

Amid the Israel-Hamas war, much of Israel's tech community is still finding a way to push forward, according to a handful of tech community members CNBC spoke with. Some have up to 45 coworkers drafted for military reserve, some have seen people join Zoom calls in military uniform on breaks from duty and some have already been to multiple military funerals.

Israel's tech community accounts for nearly one-fifth of the country's annual GDP, making it the sector with the largest economic output for the country, according to the Israel Innovation Authority.

North Gaza residents head south — with no known destination

Residents have begun to evacuate northern Gaza to head south, NBC News reports, following overnight instructions from the Israeli military to evacuate past the Wadi Gaza wetlands. Concerns have mounted that Israel plans a ground incursion into Gaza territory, in its quest to neutralize the military positions of Palestinian militant group Hamas — which carried out a deadly terrorist offensive against Israel over the weekend.

The U.N. says the civilians of north Gaza were given only 24 hours to evacuate southward — while the Israeli Defense Forces say the operation must be carried out as soon as possible. Humanitarian groups, including those under the umbrella of the United Nations and the World Health Organization, have decried the Israeli order as a shortcut to worsen the humanitarian crisis already unfolding in besieged Gaza.

"We're just going, if you have a car just run. No one knows where we're going, but we're all evacuating," Salma Shurrab, a 22-year-old student from Gaza City, told NBC News. "No one is left but us and we're ready to run."

She is one of a U.N.-estimated 1.1 million people who must now evacuate.

The Gaza Strip is surrounded by Israel, the sea, and Egypt — through the Rafah crossing. The U.S. had mentioned the possibility of creating a humanitarian corridor for refugees with Egypt, but the talks have yet to formalize into an official breakthrough.

Philippe Lazzarini, the head of the United Nations Palestinian refugee agency, on Friday estimated that over 423,000 people across the Gaza enclosure have already been displaced, with more than 270,000 of these taking shelter at UNRWA (United Nations Relief and Works Agency) sites. The figures likely also include refugees who were previously displaced.

Hezbollah deputy chief says group is ready to intervene in Israel-Hamas war

The deputy chief of Hezbhollah on Friday stressed that the Lebanese militant group is ready to intervene in the Israel-Hamas hostilities, according to the Hebzollah-affiliated al-Manar outlet.

"We will carry out our duties whenever it is high time," Naim Qassem, the second in command of Hezbollah, is quoted as saying. "Israel is tending towards its demise, Western support will make no difference."

Israel has been combating Palestinian militant group Hamas, which carried out a multi-pronged terrorist attack over the weekend.

Hamas and Hezbhollah have historically both received support from Iran — whose Foreign Minister Hossein Amirabdollahian on Friday met with Hezbollah Secretary-General Hassan Nasrallah in Beirut to discuss the Israel conflict.

Hezbollah has exchanged fire with Israel across the border over the course of this week.

Humanitarian agencies criticize evacuation of north Gaza

A spate of humanitarian agencies have spoken out since Israel gave overnight instructions to evacuate the citizens of Gaza City south of the Wadi Gaza river. The U.N. says Israeli military informed it that civilians had 24 hours to move out.

The Gaza Strip has been sealed off from Israeli food, water, fuel and electricity supplies since the start of the week, following a weekend attack from Palestinian militant group Hamas against Israel.

The latest evacuation orders have raised fears of a planned Israeli ground offensive into Gaza. The Israeli Defense Forces have yet to confirm such an operation and say their overall objective in their response is to strip away the military abilities from Hamas. Humanitarian agencies have spoken up out of concern for harm to civilians.

"The call from Israeli Forces to move more than 1,000,000 civilians living in northern Gaza within 24 hours is horrendous. This will only lead to unprecedented levels of misery and further push people in Gaza into abyss," the UN Relief and Works Agency for Palestine refugees said in a statement.

"The warnings and threats by the IOF to civilians to evacuate their homes are alarming and horrifying," the Palestine Red Crescent Society said on social media.

"The Israeli military demand that 1.2 million civilians in northern Gaza relocate to its south within 24 hours, absent of any guarantees of safety or return, would amount to the war crime of forcible transfer. It must be reversed," the Norwegian Refugee Council said.

Amid backlash, Israel's ambassador to the U.N. has accused the alliance of ignoring Hamas activity so far.

"For years now, the UN has been 'turning a blind eye' to the arming of Hamas and its use of civilians to hide its murderous instruments. And now, instead of standing by Israel after the massacre by Hamas, they dare to preach to us when Israel tries to minimize harm to civilians," Gilad Erdan said on social media on Friday, according to a Google translation.

"Right now the only thing the UN should focus on is the return of the abductees to Israel. This is the most urgent humanitarian crisis."

Iran's foreign minster, Hezbollah leader discuss Israel-Hamas war

Iran's Foreign Minister Hossein Amirabdollahian on Friday met with the leader of Lebanon's Tehran-backed Hezbollah militant group to discuss the ongoing conflict which has prompted Hezbollah and Isreal to exchange fire this week.

Amirabdollahian convened with Hezbollah Secretary-General Hassan Nasrallah in Beirut on Friday, Iran's state-run Islamic Republic News Agency reported, according to a Google translation.

A Hamas terrorist attack over the weekend has pushed Israel to declare war against the Palestinian militant group and declare a complete siege of the Gaza Strip. Fears have mounted over a potential Israeli ground incursion after Israeli military instructed the citizens of Gaza City to evacuate southwards.

Referring to the siege of Gaza, Amirabdollahian stressed: "The continuation of this war crime will face reactions in other areas," for which he said Israel and its supporters would be responsible.

Iran has previously praised the hostilities of Hamas — which it also backs — but denied involvement. Hezbollah has exchanged shelling with Israel at the border between it and Lebanon, citing solidarity with Palestine.

European Commission president arrives in Israel

European Commission President Ursula von der Leyen arrived in Israel on Friday "to express our solidarity with the Israeli people in the wake of the horrific Hamas terrorist attack" on Saturday, she said on social media.

She added that she is joined on the visit by European Parliament President Roberta Metsola.

The EU has firmly condemned last weekend's hostilities by Palestinian militant group Hamas.

The bloc's foreign chief Josep Borrell has also spoken out against the siege of Gaza, which Israel has cut off from supplies of its water, fuel, food and electricity.

Von der Leyen's arrival comes on the footsteps of a high-profile Thursday visit from U.S. Secretary of State Antony Blinken, who met with Israeli Benjamin Netanyahu and top defense and diplomacy officials.

Italy convinced that Israel will have a 'proportionate reaction'

Italy's foreign minister expressed his conviction that Israel will not strike civilians and will have a commensurate response as it reacts to Saturday's terrorist attack by Palestinian militant group Hamas.

"I am convinced that Israel will have a proportionate reaction and will do everything to hit only Hamas," Italy's Foreign Minister Antonio Tajani said Friday. He confirmed his arrival in Israel earlier in the day on social media.

His comments come after Israel gave overnight orders for the civilians of Gaza City to evacuate southwards past the Wadi Gaza river, bolstering expectations that the country's military will proceed with a ground incursion against Hamas with the troops it has amassed at the border.

Putin warns against 'serious consequences' of ground incursion in Gaza

Russian President Vladimir Putin has warned of the severe impact of a ground incursion in the Gaza Strip, amid mounting fears that Israel is preparing such an offensive following evacuation orders.

"A ground operation in the Gaza Strip and the use of heavy equipment in residential areas are fraught with serious consequences for all parties," Putin said Friday, in Google-translated comments carried by Russian state news agency Tass.

"Civilian losses in the event of a ground operation in the Gaza Strip will be unacceptable," he added.

Reuters reports that the Russian leader urged a peaceful resolution to the conflict sparked by terrorist attacks from Palestinian militant group Hamas over the weekend.

Russia's stance on the Israel-Hamas conflict has been muted, as Moscow seeks to maintain both its interests in Israel and its allegiance to Hamas-supporting ally Iran.

Putin was speaking from Bishkek, Kyrgyzstan where he is attending a meeting of the council of the Commonwealth of Independent States, an Eurasian international organization. This is Putin's first trip abroad since the issuance of an International Criminal Court warrant for his arrest on the grounds of unlawfully deporting children from occupied Ukrainian territories into Russia.

Israel's military criticizes Hamas rejection of evacuation call

The Israel Defense Forces criticized the response of the political wing of Palestinian militant group Hamas for rejecting its calls for the civilians of Gaza City to evacuate south.

"Hamas is telling Gaza residents to ignore our safety instructions," the IDF said in a social media post.

The Israeli military issued the evacuation instructions overnight, mounting fears of a potential Israeli ground incursion against Hamas positions in the Gaza Strip. Gaza is currently under total siege by Israel, following Hamas' terrorist attacks on Saturday. The U.N. said the IDF gave a 24-hour deadline for the evacuation to take place.

Hamas accused Israel of "psychological warfare" and said: "We are fixed on our land, in our homes, and in our cities ... and there is no displacement or deportation," according to a NBC News translation.

U.S. Secretary of Defense arrives in Israel

U.S. Secretary of Defense Lloyd Austin arrived in Tel Aviv, Israel on Friday, to "demonstrate that America's support for Israel's security is ironclad," he said on social media.

He will meet with Israeli Prime Minister Benjamin Netanyahu and his defense counterpart Yoav Gallant over the course of the day to discuss defense needs.

His trip follows the Thursday visit to Tel Aviv of U.S. Secretary of State Antony Blinken, who reassured Netanyahu of Washington's solidarity and ongoing assistance. Blinken has since left for Jordan.

U.S. President Joe Biden has already pledged to provide "surging additional military assistance, including ammunition, and interceptors to replenish Iron Dome" to Israel, following the terrorist offensive of Palestinian militant group Hamas over the weekend.

The Israeli Defense Forces on Thursday said that the first plane carrying U.S. arms landed in southern Israel.

Hamas armed unit says 13 captives killed in Israeli airstrikes

The al-Qassam Brigades, the armed unit of Palestinian militant group Hamas, said that 13 of its hostages were killed in the past 24 hours in Israeli airstrikes on the Gaza Strip. The toll includes foreigners, al-Qassam said in a Telegram post translated by NBC News.

CNBC could not independently verify the reports.

Hamas took civilian captives during a multi-pronged attack carried out over the weekend, which has sparked retaliatory offensives from Israel. Analysts have noted that holding hostages gives Hamas a significant bargaining chip in the event of an Israeli incursion into Gaza.

Russia may gain from Middle East crisis, analysts say, but it could backfire if war spirals out of control

Russia may find itself in a position to benefit from the escalating crisis in the Middle East, analysts told CNBC.

They cited how the Israel-Hamas war may help to distract from the Kremlin's full-scale invasion of Ukraine, boost Russia's oil-exporting status and provide Moscow with an opportunity to mediate between disparate regional parties.

However, one geopolitical analyst warned it is also a "very, very nervous moment for Moscow," particularly if the Israel-Hamas conflict spills over and Russia sees its influence, interests and assets damaged in the Middle East.

Israeli military says its ongoing goal is to 'strip away' Hamas' military abilities

The aim of the Israeli campaign in the Gaza Strip is to "take all of Hamas' military abilities and strip them away" to avoid further Israeli civilian casualties, Jonathan Conricus, spokesperson for the Israeli Defense Forces, said in a video update released early Friday.

"That is the purpose of what we are doing now inside the Gaza Strip. That is why the Israeli air force has been delivering significant amounts of ordinance of bombs on the Gaza Strip. And that is what we will continue to do as this war unfolds and as we will deal a decisive blow to Hamas," he added.

Hours prior, the IDF told roughly 1.1 million people in northern Gaza to evacuate southwards of the Wadi Gaza wetlands.

"This evacuation is for your own safety. You will be able to return to Gaza City only when another announcement permitting it is made," the IDF said in the message it distributed on Telegram, which it said it communicated to the civilians of Gaza City. The instruction to evacuate has bolstered concerns that Israel, which has amassed forces on the border with Gaza, is preparing a ground incursion.

The Telegram post did not reference a 24-hour deadline — a timeframe that the U.N. said the IDF supplied them for the operation.

"We understand that this will take time," Conricus said in the video update. "It's not an easy process."

UN refugee agency relocates Gaza premises

The U.N. Agency for Palestine Refugees (UNRWA) has relocated its central operations in Gaza to the south of the territory as it continues with its local humanitarian work.

In a post update on the X social media platform, previously known as Twitter, it urged Israeli authorities to protect all civilians who take cover in its shelters, including schools.

Earlier in the week, the U.N. said that schools and premises of the UNRWA were among the sites hit in Israeli retaliatory air strikes that followed a terrorist attack by Palestinian militant group Hamas at the weekend. Twelve UNRWA staff members have been killed since the start of the conflict, the agency said Thursday.

Its operational relocation south takes place as the U.N. said Israel has supplied a 24-hour deadline for the roughly 1.1 million people in northern Gaza to evacuate south.

Israel's use of white phosphorus in Gaza and Lebanon endangers civilians, says HRW

Israel's use of white phosphorus in military operations in Gaza and Lebanon puts civilians in danger as it exposes them to severe and long-lasting injuries, Human Rights Watch warned.

"White phosphorus, which can be used either for marking, signaling, and obscuring, or as a weapon to set fires that burn people and objects, has a significant incendiary effect," the non-governmental organization said, noting it can burn people and objects, as well as set on fire structures and fields in the vicinity.

Human Rights Watch said the rights group witnessed videos taken in Lebanon and Gaza this week that showed a number of airbursts of artillery-fired white phosphorous over the Gaza City port and two rural locations along the Israel-Lebanon border.

Using the substance violates international humanitarian law which prohibits putting civilians at unnecessary risk, HRW said.

"Any time that white phosphorus is used in crowded civilian areas, it poses a high risk of excruciating burns and lifelong suffering," said Lama Fakih, Middle East and North Africa director at Human Rights Watch.

IDF confirms it has ordered civilians in Gaza to move south 'for their own safety'

Israel Defense Forces confirmed it has ordered civilians in northern Gaza to evacuate south "for their own safety."

"Gaza City is an area where military operations are taking place," IDF spokesman Jonathan Conricus said in a post on X, formerly known as Twitter.

"This evacuation is for your own safety," he said, adding that residents will only be able to return when another announcement permitting them to do so is made.

He repeatedly warned that they should not approach the border with Israel.

"Hamas terrorists are hiding in Gaza City, inside tunnels, underneath houses and inside buildings populated with innocent Gaza civilians," Conricus said, calling on Palestinians to distance themselves from the militants who are using them as human shields.

Death toll mounts

The latest figures show further increases in the total number of people killed following Palestinian militant group Hamas' multi-pronged attack last Saturday and Israel's retaliatory strikes.

At least 1,300 people have been killed in Israel since the hostilities, according to official figures, with another 3,300 wounded.

A combined 1,568 people have been killed in the Gaza Strip and the West Bank over the same period, official figures show.

It should be noted that there can be discrepancies between the figures reported by various official sources, as events continue to develop on the ground.

UN says Israel wants 1.1 million people in Gaza to move south in the next 24 hours

Israel has called for the evacuation of 1.1 million residents in north Gaza to move south in the next 24 hours, Stephane Dujarric, spokesman for the UN secretary-general, confirmed with NBC News.

"The United Nations considers it impossible for such a movement to take place without devastating humanitarian consequences," the statement said.

The entire population of Gaza north of Wadi Gaza has been ordered to relocate to southern Gaza "within the next 24 hours," the Israeli military informed the UN and the Department of Safety and Security in Gaza  before midnight local time.

That's 1.1 million people — about half the size of Gaza Strip's population.

The move suggests that Israel could be moving to proceed with its ground offensive into the Palestinian enclave to pursue Hamas militants that the Jewish nation has pledged to wipe out.

The same order was given to all of UN's staff and those taking refuge in UN facilities, such as schools, medical centers and clinics.

No plans to put U.S. forces on the ground in Israel, White House says

National Security Council spokesman John Kirby said that while the U.S. will continue to evolve its strategic planning around the ongoing Israel-Hamas conflict, there are no plans to put American servicemembers on the ground in Israel.

"There are no intentions, no plans to put American troops on the ground in combat," Kirby told reporters at the White House during a press briefing. "There is no interest from the Israelis," he added.

A senior Defense official, who spoke on the condition of anonymity per ground rules established by the Pentagon, echoed Kirby's remarks in a separate briefing with reporters.

"We are consistently and continuously consulting with them on their needs. What they have asked of us is to expedite security systems so that they are able to defend themselves," the official said.
