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.

Hamas said it is seeking an end to the war and the unrestricted entry of humanitarian aid as it is expected to announce a decision on a new U.S. ceasefire proposal to which U.S. President Donald Trump said Israel had agreed.

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.
