The United States on Monday praised Saudi Arabia for “exposing” Iran’s role in Yemen and Tehran’s provision of missile systems to Houthi rebels fighting there.

“We continue to maintain strong defense ties with the Kingdom of Saudi Arabia and work together on common security priorities to include combat operations against violent extremist organizations, and neutralizing Iran’s destabilizing influence in the Middle East region,” said Pentagon spokesman Marine Major Adrian Rankine-Galloway, according to Reuters.

The comments come after Saudi Arabia said Iran was behind a missile fired by the Houthis toward the Saudi capital Riyadh on Saturday.
