Netanyahu, who polls show in a tight race to stay in power in the Oct 27 election, has been hammered by the opposition for failing to prevent the attack, the deadliest day in Israeli history.

Netanyahu, who has cast himself as a guarantor of Israel's security over his decades-long career, has insisted that he could have stopped the attack had the Shin Bet's then director, Ronen Bar, or military leaders called to wake him up the day of the early-morning attack.
