JERUSALEM — Israeli Prime Minister Benjamin Netanyahu vowed revenge Friday for what he described as a “cruel and malicious violation” of the ceasefire agreement after a body that Hamas released as part of the deal was found to not be that of an Israeli mother of two young boys, as the militants had promised.

Israeli specialists said one of the four bodies handed over by Hamas on Thursday was not Shiri Bibas, whose two sons, Kfir and Ariel were handed over.

Israeli Prime Minister Benjamin Netanyahu on Friday said he would ensure "Hamas pays the full price" for failing to hand over hostage Shiri Bibas after the militant group released a body Israel said was not hers.
