Iran fired cruise missiles in attack on Saudi oil facility: Senior US official

Iran launched nearly a dozen cruise missiles and over 20 drones from its territory in the attack on a key Saudi oil facility Saturday, a senior Trump administration official told ABC News Sunday.

It is an extraordinary charge to make, that Iran used missiles and drones to attack its neighbor and rival Saudi Arabia, as the region teeters on the edge of high tensions.

President Donald Trump warned the U.S. was "locked and loaded" to respond to the attack on Sunday, waiting for verification of who was responsible and for word from Saudi Arabia on how to proceed.

The Trump administration, in particular Secretary of State Mike Pompeo, has blamed Iran for the attack since Saturday, but so far, there's been no public accusation that Iran launched missiles.

The Houthi rebels in neighboring Yemen claimed responsibility for the assault, which hit one of the world's largest oil processing facilities, hundreds of miles from the Yemen-Saudi border, and sharply impacted global oil supplies.
