The United States has called on the United Nations to act against Iran after Saudi Arabia, a Washington ally, accused Tehran of "direct military aggression" through the Houthi rebels in Yemen.
Amid an escalating war of words, Saudi Crown Prince Mohammed bin Salman on Tuesday pointed the figure to Iran for supplying a ballistic missile that was fired on Saturday from Houthi-held territory towards Riyadh's international airport.
Saudi-led forces, which have been fighting the Houthis since March 2015, intercepted and destroyed the weapon before it reached its target.
Iran, which supports the Shia Houthi rebels but denies arming them, has dismissed the Saudi allegation as "contrary to reality".
Nikki Haley, the US ambassador to the UN, on Tuesday accused Iran of supplying a missile to the Houthis that was fired into Saudi Arabia in July, and also referred to Riyadh's allegation that the weapon that was shot down over Riyadh on Saturday "may also be of Iranian origin".
"By providing these types of weapons to the Houthi militias in Yemen, Iran's Islamic Revolutionary Guard Corps is violating two UN resolutions simultaneously," Haley said.
"We encourage the United Nations and international partners to take necessary action to hold the Iranian regime accountable for these violations."
