Israel called again on Saturday for civilians to leave parts of the city.
As the Israel-Hamas war crosses the seven-month mark, renewed negotiations are underway to secure the release of hostages taken by the terrorist organization, as Israeli forces continue to prepare for an apparent invasion of the southern Gazan town of Rafah.
Hamas' delegation has arrived in Cairo as cease-fire negotiations continue with mediators in Egypt and Qatar.
Hamas said Monday it had agreed to a cease-fire deal, but Israel said the agreement included "significant gaps" that needed to be worked out in negotiations.

The Biden administration is delaying shipments of ammunition that were expected to be sent to Israel, according to three U.S. officials.
The Biden administration has been trying to pressure Israel to hold off on a full-scale invasion of Rafah until it has a plan to protect the million civilians now living there.
The Air Force has been told by the White House’s National Security Council to pause shipments of ammunition deliveries specifically from Dover Air Force Base, according to a U.S. official. The NSC was behind the decision to pause the munitions, a second U.S. official confirmed.
The National Security Council did not immediately respond to a request for comment.

House Speaker Mike Johnson and Majority Leader Steve Scalise have publicly accused the Biden administration of withholding aid to Israel following reports that some aid shipments have been halted. Johnson said that the Biden administration as recently as Friday had assured his staff that there would be "no delay" in assistance to Israel.
Johnson said he received a report this morning from on the ground in Israel that said "a shipload of munitions and precision weapons, which are to be used to help protect civilians and Rafah, is being withheld."
In a letter to President Joe Biden, Senate Republicans Jodi Ernst and Ted Budd said they are "shocked" and "deeply concerned" that the Biden administration failed to notify Congress before withholding ammunition to Israel.
"If these reports are true, then you have once again broken your promise to an American ally," they said.

In his first comments since Israel's offensive into Rafah began, Prime Minister Benjamin Netanyahu said that Hamas' cease-fire proposal on Monday was "intended to torpedo the entry of our forces into Rafah."
"It did not happen. As the War Cabinet unanimously determined, the Hamas proposal is very far from Israel's necessary requirements," Netanyahu said.
"I instructed the working-level delegation that went to Cairo: continue to stand firm on the conditions necessary for the release of our abductees, continue to stand firm on the essential requirements for guaranteeing Israel's security," Netanyahu said.
