A SCUD-type of missile, launched by Yemen-based Houthi rebels flew hundreds of miles in Saudi Arabia according to US defense officials. And even more concerning to government officials was that the missile flew farther in range than anything the rebels had used before and that Iran supplied it.

The missile, described by one official as a Scud, was fired from Houthi controlled territory near Sa’Dah in northern Yemen and flew some 930 kilometers before landing near the western coast of Saudi Arabia.

It is assessed that the target was a Saudi oil facility near the port city of Yanbu.

One official told CNN that the missile launch was concerning because it flew farther than any other missile fired by the Houthis.
