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.

Israeli airstrikes killed 15 Palestinians in Gaza early on Friday, while another 20 people died in shootings while waiting for aid, the hospital morgue that received their bodies told The Associated Press.

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.
