TEL AVIV, Israel — The head of Israel’s military intelligence directorate resigned on Monday over the failures surrounding Hamas’ unprecedented Oct. 7 attack, the military said, becoming the first senior figure to step down over his role in the deadliest assault in Israel’s history. [time-brightcove not-tgx=”true”] Maj. Gen. Aharon Haliva’s resignation sets the stage for what’s expected to be more fallout from Israel’s top security brass over Hamas’ attack, when militants blasted through Israel’s border defenses, rampaged through Israeli communities unchallenged for hours and killed 1,200 people, most civilians, while taking roughly 250 hostages into Gaza.
