Shiri Bibas was kidnapped with her two sons — Ariel, 4, and Kfir, 9 months old — from their home on Kibbutz Nir Oz on Oct. 7, 2023

Hamas released their bodies last week as part of a fragile ceasefire deal

Though initially the militant group did not release the correct body for Shiri Bibas, testing had confirmed the identities of the three others but found the remains said to be the mother was instead an unidentified Palestinian woman

Prime Minister Benjamin Netanyahu accused Hamas of a "cruel and malicious violation" of the ceasefire and vowed revenge

Yarden Bibas, their father, was taken separately, and released during the ceasefire last month

Hamas says the three were killed in an Israeli airstrike in November 2023

Israeli military spokesperson Rear Adm. Daniel Hagari denies this and said Ariel and Kfir Bibas were killed by their captors

The three will be buried on Kibbutz Nir Oz on Wednesday afternoon

The breakthrough appeared in ceasefire to clear the way for the return of the bodies of four more dead hostages and hundreds of additional prisoners scheduled to be released under the ceasefire

The prisoners previously slated for release 'will be released simultaneously with the bodies of the Israeli prisoners who were agreed to be handed over,' along with the release of a new set of Palestinian prisoners, the statement said
