In a statement on Monday, Rouhani instructed the relevant organizations to implement the resolution, which was passed during an open session of the parliament on Tuesday.
The resolution has been endorsed by the Guardian Council.
The lawmakers unanimously voted for the emergency motion to designate the US forces as terrorists in response to a recent move by Washington to assassinate Iran’s revered commander, Lt. General Qassem Soleimani.
General Soleimani, Abu Mahdi al-Muhandis, who was the deputy head of Iraq’s Hashd al-Sha'abi (PMU), and a number of their entourage were killed in a strike by American drones near Baghdad International Airport on Friday, January 3.
The White House and the Pentagon claimed responsibility for the assassination of General Soleimani in Iraq, saying the attack was carried out at the direction of US President Donald Trump.
