Hamas is under pressure from Israel and the U.S. at a crucial time for the Gaza ceasefire as it claims it could have misidentified a hostage's remains.

Hamas has turned over the bodies of four slain Israeli hostages more than 500 days after the terrorist group's Oct. 7, 2023, attack in Israel.

The handover marks the first return of the bodies of captives under the ceasefire agreement between Hamas and Israel that took effect last month and will also see hundreds of Palestinians released from Israeli jails, where allegations of abuse and torture are widespread and where many have been kept in detention without any charge or trial.
