Iran's Supreme Leader Mojtaba Khamenei has vowed revenge for the killing of security chief Ali Larijani in a US-Israeli strike on Tuesday. Assuring that justice will be served, he warned that 'every drop of blood has a price' that the US and Israel must pay. "Such acts of terror only reflect the enemies' hostility and will strengthen the resolve of the Islamic nation. Undoubtedly, justice will be served," he said in a statement. In his statement, Mojtaba claimed that Larijani was a "learned, far-sighted, intelligent" individual with diverse experiences in many fields. He said that the assassination of such an individual showed how important he was and the "hatred of the enemies of Islam towards him". He threatened "anti-Islamists" and said, "Shedding this blood at the foot of the tree of the Islamic system only makes it stronger, and of course, every blood has a price that the criminal murderers of the martyrs must pay soon."
