Iran has accused the United States of being responsible for "atrocities" in Yemen through its support for Saudi Arabia, which is leading a coalition to fight Tehran-backed Huthi rebels.
Iran's Foreign Ministry spokesman Bahram Ghassemi said a White House statement on November 24 in support of Riyadh "clearly and without question proves America's participation and responsibility” in what Tehran described as “atrocities committed by Saudi Arabia in Yemen."
In its statement, Washington said it was "committed to supporting Saudi Arabia... against the Iranian Islamic Revolutionary Guard Corps' aggression and blatant violations of international law."
In early November, Riyadh accused Tehran of "direct aggression" after Saudi forces intercepted a missile fired by Huthi forces towards Riyadh's international airport.
Iran is ruled by conservative Shi’ite clerics while Tehran’s archrival in the region, Saudi Arabia, is a Sunni Muslim majority kingdom.
The two Gulf states back opposing sides in conflicts from Yemen to Syria.
Tehran and Riyadh cut diplomatic relations in January 2016 after Iranian protestors stormed Saudi diplomatic missions in reaction to Riyadh's execution of a prominent Shi’ite cleric.
