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.
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.

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.

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.

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.

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."

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.

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.

"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.

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.

"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.

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.
