Israeli Prime Minister Benjamin Netanyahu is facing mounting accusations that he ignored warnings ahead of the October 7, 2023 Hamas attack, as a bitter blame game over one of Israel’s worst security failures emerges in the final weeks of the election campaign.

Former Shin Bet chief Ronen Bar has filed a defamation suit against Netanyahu, accusing him of falsely blaming intelligence officials for the attack despite receiving repeated alerts about security threats.

The Hamas-led assault killed around 1,200 people in southern Israel, with another 251 taken hostage. Israel’s subsequent military offensive in Gaza has killed more than 74,000 Palestinians, according to the local health authorities.

Bar is seeking nearly $1 million in damages, claiming he warned the prime minister of growing danger in the months preceding the assault. He says a long trail of documents will expose Netanyahu’s account of events as false.

“Israel’s worst disaster has become political kryptonite,” RT correspondent Charlotte Dubenskij reported from Jerusalem on Friday, as the country prepares to vote on October 27.

Netanyahu, however, maintains that Bar failed to alert him to the imminent threat on the morning of the attack, despite discussing warning signs with senior military officials. He has accused the former intelligence chief of failing to take measures that could have prevented the bloodshed.

Further questions have been raised by Netanyahu’s former military secretary, Avi Gil, who claims officials attempted to alter the recorded time of a phone call made on the morning of October 7.

The prime minister has also denied reports that he received advance warnings from Egyptian intelligence and UAE President Mohamed bin Zayed. The claims have drawn criticism from political rivals, including former Prime Minister Naftali Bennett and former military chief Gadi Eisenkot.

Questions have also emerged over Netanyahu’s handling of the subsequent Gaza war. Former Israeli hostage negotiator Nitzan Alon has suggested that political considerations delayed a deal that could have brought captives home much earlier.
