The United States on Wednesday accused Iran of supplying Yemen's Houthi rebels with advanced weapons, including ballistic missiles, echoing allegations made by Saudi Arabia.
A White House statement condemned Iran's actions and voiced US support to Saudi Arabia and other Gulf partners against Tehran's "blatant" violations of international law.
It says missile systems were not present in Yemen before the civil war, alleging that Iran provided them. The statement also urged the United Nations to review evidence that Iran is perpetuating the war in Yemen to further its regional ambitions.
Iran supports the Houthis but has denied arming them.
