Just what happened to Shiri Bibas and her two children after they were kidnapped on October 7, 2023, has become a source of torment for their family and millions of Israelis.

Israel accused Hamas of a breach of the cease-fire agreement between the warring sides of the "utmost severity" after forensics tests showed the body of an 'Israeli hostage' returned was a Palestinian woman.

Hamas originally claimed in November 2023 the three members of the Bibas family had been killed in an Israeli air strike, without providing evidence. The BBC hasn't been able to independently verify this. Israel says it will not confirm their deaths before forensic testing.
