The United States has put forward a new proposal that would secure the release of a handful of living hostages held by Hamas in exchange for a month-long extension of the Israel-Hamas ceasefire, a source familiar with the negotiations said.

Hamas said on Friday it agreed to release an American-Israeli dual national, believed to be the last living American hostage held in Gaza, after receiving a proposal from mediators to continue negotiations on the second phase of a ceasefire deal.

Hamas says it will release American Israeli Edan Alexander and the bodies of four other hostages only if Israel implements their cease-fire agreement.
