SANAA: A Saudi-led coalition fighting rebels in Yemen said a ballistic missile intercepted over southern Saudi Arabia on Friday served as proof Iran supported Al Houthi militants.

“This hostile act by the Iran-backed Al Houthis proves the Iranian regime remains implicated in supporting the armed Al Houthis,” Saudi Arabia's state news agency SPA quoted a coalition statement as saying.

Saudi state TV says its air defense system intercepted the missile above Najran in the kingdom’s southwestern region.

The militants have previously fired missiles targeting the Saudi mainland, including the capital, Riyadh, and the city’s international airport.

Saudi Arabia backs Yemen’s internationally-recognised government and leads an international coalition at war with the militants since March 2015.

The coalition has repeatedly accused Iran of arming Al Houthis.
