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.

Hamas is expected to respond positively to the US-backed proposal for a ceasefire with Israel in the Gaza Strip and the release of hostages.
