The body of Israeli hostage Shiri Bibas has been returned to Israel after Hamas sent back the wrong human remains.

Hamas freed two hostages and was set to release four more from Gaza on Saturday in exchange for hundreds of Palestinian prisoners and detainees, after Israel confirmed that a body handed over hours earlier was that of hostage Shiri Bibas.

Hamas on Thursday put on a macabre handover ceremony in central Gaza to return the bodies of four Israeli hostages taken on October 7, 2023.

Israel on Friday accused Hamas of a breach of the cease-fire agreement between the warring sides of the "utmost severity" after DNA testing of four sets of hostage remains returned on Thursday showed one of the bodies was not that of Shiri Bibas as Hamas had claimed.

Hamas frees more Israeli hostages from the Gaza Strip; a body militants delivered overnight has been identified as that of Israeli mother Shiri Bibas.

The remains of the youngest and one of the oldest captives seized by Hamas during the attack that ignited the war in the Gaza Strip are expected to be returned Thursday, an Israeli official said Wednesday.

Israel has confirmed the identities of the four deceased hostages set to be released on Thursday as Shiri Bibas, her two children, and Oded Lifshitz.

When Hamas returns the bodies of four hostages this week, they'll include the two youngest hostages taken, reports the BBC. The group said three of the four bodies are those of Shiri Bibas and her two children—Kfir,

Israelis had hoped against hope that the family, taken when the youngest was just nine months old, had survived their captivity.

Hamas said it would turn over the bodies of the boys, Ariel Bibas and his baby brother, Kfir, and their mother. Israel was expected to release Palestinian prisoners in exchange.
