U.S. and Arab mediators made significant progress overnight toward brokering a ceasefire in the Israel-Hamas war and the release of scores of hostages held in the Gaza Strip, but a deal hasn't been reached yet,

Hamas is expected to release 33 hostages during the first phase of an emerging ceasefire agreement being finalized by negotiators in Doha, two Israeli officials said.

Progress in cease-fire talks has raised hopes a deal could be reached to release some of the hostages still held in the Gaza Strip and pause fighting that has dragged on for 15 months.
