Hamas says it has accepted a proposal from mediators to release one living American-Israeli hostage and the bodies of four dual-nationals who had died in captivity.

Hamas said it’s willing to release all American-Israeli hostages, including one still alive, in a surprise move dismissed by both Israel and the US as unhelpful to negotiation efforts to end the war.

Hamas says it’s prepared to release U.S.-Israeli hostage Edan Alexander, who’s believed to be the last living U.S. citizen held in Gaza, along with the bodies of four other dual nationals. CNN’s Jeremy Diamond reports from Tel Aviv.
