“Today’s dawn attack on Syria is a crime. I clearly declare that the president of the United States, the president of France and the British prime minister are criminals,” Khamenei said in a speech, according to his Twitter account.
“They will not benefit (from the attack) as they went to Iraq, Syria and Afghanistan in the past years and committed such crimes and did not gain any benefits,” Khamenei added.
Iran — the dominant Shi’ite Muslim power which is in rivalry with Saudi Arabia and the United States’ other Sunni Arab allies — has been Syrian President Bashar al-Assad’s most supportive ally against insurgents throughout the conflict.
Militias backed by Tehran helped Assad’s army stem rebel advances and, following Russia’s entry into the war in 2015, turn the tide decisively in the Syrian government’s favour.
