The remains of three people handed over by Hamas to the Red Cross this week did not belong to any of the hostages, an Israeli source told CBS News on Saturday. It is the latest setback that could undermine the U.S.-brokered ceasefire between Israel and Hamas .

The unidentified remains of the three people were returned late Friday to Israel, where they were examined overnight. At the time, a military official told the Associated Press that Israeli intelligence suggested they did not belong to any of the hostages taken by Hamas terrorists during the Oct. 7, 2023 terror attack in southern Israel that sparked the war. The Israeli official spoke on condition of anonymity because they were not authorized to talk to the media.
