Yemen's Houthi movement declared that it has launched armed drones to attack Abha Airport as well as the King Khalid Airbase in the southern town of Khamis Mushait, Saudi Arabia.
"It is part of our legitimate right to respond to the crimes of the aggression and its continuing blockade", a military spokesman for the group Yahya Sarea said on Twitter.
Yemen has been mired in a civil war between government forces led by President Abdrabbuh Mansour Hadi and the Houthis since 2014. The Saudi-led coalition of Arab states supported Hadi in the conflict, and has been conducting operations in the country at his request since March 2015.
