According to a report by the Telegraph, Mossad, Israel’s intelligence agency, hired Iranian security agents to plant explosives in 3 separate rooms of a building where a leader of Hamas was staying. Iran’s Revolutionary Guards say Ismail Haniyeh was killed in Tehran by a short-range projectile. Iran has since vowed revenge for the death of Haniyeh. He was a Hamas leader and was a negotiator in Gaza ceasefire talks.
