Israel-Gaza updates: Harris to meet with Israeli war Cabinet member on Monday

After suggesting a cease-fire between Hamas and Israel could happen by Monday, U.S. President Joe Biden is now indicating it may take longer to reach a deal, without offering a new timeline.

"Probably not by Monday, but I'm hopeful," Biden told reporters on Thursday. "Hope springs eternal."

The United States, along with Egypt and Qatar, has been mediating talks between the warring sides.

Biden spoke on the phone Thursday with the emir of Qatar and the president of Egypt. All leaders agreed that Hamas should release the hostages "without delay" and that it would result in "an immediate and sustained cease-fire in Gaza over a period of at least six weeks," according to a White House readout.

Biden also thanked Egyptian President Abdel Fattah El-Sisi for delivering humanitarian aid to Gaza and plans to surge more assistance to the region.

Israeli forces allegedly opened fire on hungry Palestinians who were waiting for food aid in the northern Gaza Strip on Thursday morning, according to a spokesperson for Gaza's Hamas-run Ministry of Health.

At least 112 people were killed and 760 others were injured in the incident at Al-Nabulsi roundabout near Al-Rashid Street in the southwest of Gaza City, the health ministry spokesperson said in a statement, adding that the death toll was expected to rise as dozens of the wounded were in critical or serious condition. Patients from the incident who were admitted to Al-Shifa Hospital in Gaza City suffered from injuries consistent with gunshot wounds, being hit by tank artillery shells and being trampled, according to the health ministry spokesperson.

When asked for comment, the Israel Defense Forces told ABC News on Thursday: "Early this morning, during the entry of humanitarian aid trucks into the northern Gaza Strip, Gazan residents surrounded the trucks, and looted the supplies being delivered. During the incident, dozens of Gazans were injured as a result of pushing and trampling. The incident is under review."

Israeli security officials told ABC News on Thursday that the crowd approached IDF troops securing the passage of aid trucks in a manner that posed a threat to the troops, who responded with live fire. There was no use of artillery fire, airstrikes or drone strikes in the incident, according to Israeli security officials.

Northern Gaza has been isolated by the Israeli military and almost completely cut off from humanitarian aid for weeks, according to the United Nations, which continues to warn about the threat of famine for people still living there.

One of the truck drivers who delivers humanitarian aid to northern Gaza, Ahmed Ayad, told ABC News on Wednesday that crowds of people waiting for food aid on Al-Rashid Street block the vehicles from reaching their final destination, prompting Israeli soldiers to open fire.

"They fire so that we can advance comfortably," Ayad said. "But people don't respond to the shooting, so they move toward us and take aid from the truck. They're waiting. Everyone is anxious and the amount [of food] arriving is not enough."

U.S.President Joe Biden said Thursday that the White House is looking into the reports of Israeli forces killing civilians.

"There are two complete versions of what happened. I don’t have an answer yet," Biden said, adding that this will complicate the cease-fire negotiations.

The Biden administration is considering airdropping aid into Gaza, a U.S. official told ABC News.

More than 30,000 people have been killed in the Gaza Strip since the latest outbreak of war between Hamas and Israel began on Oct. 7, according to Gaza's Hamas-run Ministry of Health.

Over 70,000 others have been injured in Gaza since Oct. 7, the health ministry said in a statement on Thursday morning.

Of those killed, 75% are children, women and elderly people, according to a separate statement from Hamas.

The World Health Organization, the global health arm of the United Nations, also confirmed the grim milestone with Director-General Tedros Adhanom Ghebreyesus writing in a post on X, the social media platform formerly known as Twitter, that "a large majority" of those killed in Gaza are "women and children."

Tedros called for a cease-fire, saying: "This horrific violence and suffering must end."

U.S. Department of State spokesperson Matt Miller had no comment on Hamas' calls for a march on Al-Aqsa Mosque in Jerusalem, but Miller did call on the Israeli government to allow worshipers to access the site during the holy month of Ramadan, stressing it was in Israel's national security interest to avoid fueling tension in the occupied West Bank.

"I don’t have any comment on the call for marches," Miller said during a press briefing Wednesday. "I would just say, as it pertains to Al-Aqsa, we continue to urge Israel to facilitate access to Temple Mount for peaceful worshipers during Ramadan, consistent with past practice."

When asked whether the United States had received assurances that Israel -- a close ally -- would allow such access, Miller told reporters that the Biden administration was aware of "plans under consideration," but said he did not know if a final decision had been made.

"It's not just the right thing to do, it’s not just a matter of granting people religious freedom that they deserve, to which they have a right, but it's also a matter that directly is important to Israel’s security," he added.

The United States, along with Egypt and Qatar, has been mediating talks between Hamas and Israel since the war began.
