Saudi Air Force says it shoots down a missile fired by Houthi rebels from inside Yemen

The Saudi-led coalition battling rebels in Yemen says Saudi Arabia's Air Force has shot down a ballistic missile directed at the kingdom's southern border.

The coalition statement said Sunday that Shiite rebels, known as Houthis, fired the missile overnight from Yemen's capital city of Sanaa toward Saudi Arabia's southwestern border city of Najran.

The coalition said the Saudi Air Force reacted immediately and destroyed the launching pad inside Yemen. It was the second time in under a week that Saudi Arabia says Houthis have fired scud missiles toward its territory.

Saudi Arabia and its Arab allies in the Gulf have been bombing the Houthis since late March after the rebels overran the capital and other major Yemeni cities, forcing the internationally-backed government to temporarily flee the country.
