An Iranian official said Iran has not yet begun its retaliation against Israel because it wants to conduct an investigation on the security breach that caused Hamas leader Ismail Haniyeh’s assassination and because of the presence of US military in the region.

Iran has threatened Israel with a major response after Haniyeh was killed while staying at an IRGC guest house while he was attending the inauguration of new president Masoud Pezeshkian.

Although Israel has not claimed responsibility for Haniyeh’s assassination, the Jewish State is assumed to have been behind his death.
