Iran has warned Israel that it will “pay the price” after allegedly killing a top Iranian Revolutionary Guards Corps (IRGC) adviser in Syria. Iran’s state television interrupted its regular news broadcast to announce that Sayyed Razi Mousavi had been killed in Syria. IRNA said Mousavi was one of IRGC’s most senior advisers in Syria, and was killed in an airstrike near Damascus on December 25. Iranian President Ebrahim Raisi responded sharply to Mousavi’s death, saying Israel would “certainly pay the price.”
