Israel's domestic security agency Shin Bet acknowledged its failure in preventing Hamas's attack on October 7, 2023, which left hundreds dead and sparked a devastating war in the Gaza Strip. The agency's chief takes responsibility for the failures and calls for a broader probe into the role of Israel's security and political elements. The investigation found that the Shin Bet had a deep understanding of the threat from Hamas but failed to recognize the immediate threat and treat prior knowledge of the attack as actionable. The military inquiry also noted flaws in the army's intelligence assessments of Hamas.
