At least 15 Palestinians were killed overnight in an Israeli airstrike in Gaza, according to local health officials, as U.S. President Donald Trump said he expected Hamas to respond to his "final proposal" for a ceasefire in Gaza in the next 24 hours.

Israel has accepted the latest Gaza ceasefire and hostage release proposal, according to an Israeli official, who said Wednesday the updated framework provides stronger US assurances about ending the war.

New video shows several blasts lighting up the sky over the Gaza Strip early Friday morning. Health officials in Gaza said about half of those killed were women and children, with many waiting for aid.
