The mother of a woman abducted with her two children and husband was not among the slain hostages returned to Israel by Hamas on Thursday, Israel said.

After Israeli officials conducted forensic analysis to confirm the identities of the bodies, the IDF said the bodies of Lifshitz and Shiri Bibas' two children were identified. But

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.
