Israeli Prime Minister Benjamin Netanyahu has vowed “revenge” after one of the four bodies handed over from Gaza to Israel on Thursday did not include a hostage. The Israel Defense Forces called it a "very serious violation" by Hamas After Israeli officials conducted forensic analysis to confirm the identities of the returned bodies only to discover the remains of Lifshitz and Shiri Bibas' two children were identified, but the fourth body was not Shiri Bibas -- nor was it a match for another hostage, the IDF said. “The cruelty of the Hamas monsters knows no bounds,” Netanyahu said in the statement released Friday.
