(Reuters) -The Saudi-led coalition fighting in Yemen late on Sunday asked civilians in Yemeni ministries in the Houthi-controlled capital Sanaa to immediately evacuate, the state news agency (SPA) said, citing the coalition.

       The coalition said the Iran-backed Houthis use these headquarters to "launch hostile operations," and in response to the threat a site linked to the latest attack on Saudi Arabia's Abha international airport would be destroyed.

       Twelve people were injured at the airport by shrapnel from an explosive-laden drone intercepted by Saudi air defences on Thursday. Houthi military spokesperson Yahya Sarea said the group had hit a military target at Abha airport with a Qasef 2 drone.

       The Saudi-led coalition has been fighting the Houthis since early 2015 after the group ousted Yemen's internationally recognised government from power in Sanaa.
