Hamas leader Haniyeh is killed in Iran by alleged Israeli strike

Beirut, Aug.1:

Hamas leader Ismail Haniyeh was killed by a predawn airstrike in the Iranian capital Wednesday, Iran and the militant group said, blaming Israel for a shock assassination that risks escalating the conflict even as the U.S. and other nations were scrambling to prevent an all-out regional war. Iran's supreme leader vowed revenge against Israel.
