A recent investigation reported by Haaretz reveals that the Shin Bet was not aware of the Nova music festival in Re'im on the night of October 6-7, 2023, despite having a representative present at police and military discussions about the event in the days before. The representative did not relay information about the festival to Shin Bet management for reasons that remain unclear, leading to the festival's omission from security assessments that night. Multiple sources indicate that the military also failed to inform Shin Bet about the large gathering near the border, and the agency's leadership only became aware of the event several hours after the attack began, as reports of casualties emerged. A senior security official suggested that prior knowledge of the festival could have impacted the decisions made by both Shin Bet and the wider security establishment.
