At least 20 Palestinians were killed on Friday 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 U.S. President said Israel “agreed to the necessary conditions to finalize” a 60-day ceasefire, “during which time we will work with all parties to end 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.
