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.

The Hamas militant group said Friday it has issued a "positive response" to a U.S.-mediated ceasefire proposal​ in its war with Israel.

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.
