The Houthi fighters have carried out waves of strikes on Riyadh's airport, including an attack this month that killed 13 people and wounded more than 300.

Saudi Arabia, which leads a military coalition fighting the Iran-backed Houthis, has faced a barrage of strikes from the group in recent weeks.

The fighting erupted after a years-long truce between the Houthis and Yemen's Riyadh-backed government fell apart, and has shifted the focus of the wider US-Iran war.

Riyadh's international airport said flights would resume on Sunday after a two-week closure following the Houthi strikes.
