”Israel’s Shin Bet security agency has said it “failed in its mission” to prevent Hamas’ October 7 attack by ignoring repeated warning signs.
Shin Bet’s chief, Ronen Bar, said in a statement that if Shin Bet had “acted differently in the years leading up to the attack and on the night of the attack (…) the massacre would have been prevented.”
he security agency received a sequence of signs that Hamas was preparing for an emergency, but decided the militant group were “not interested in escalation” and the plans were never perceived as an active threat, Shin Bet said.
