Was Haniyeh Behind October 7 Attack On Israel? While Hamas' Gaza leader Yahya Sinwar is believed to have been the mastermind of the attacks, Haniyeh, seen as a more moderate force in Hamas, lauded them as a humiliating blow to Israel's aura of invincibility. Hours after the October 7 attacks, Haniyeh appeared in a video released by Hamas leading prayers with other top Hamas officials.
They thanked God for the success of the attack, which blasted through Israel's vaunted defences and resulted in the deadliest assault in Israel's history, according to the AP report. Michael Milshtein, a Hamas expert at Tel Aviv University, said Haniyeh had a commanding role in the group's foreign policy and diplomacy, but was less involved in military affairs.
