Analysts say Riyadh and Abu Dhabi differ over how to move forward in Yemen. The UAE, the kingdom's main military ally on the ground for most of the war, in June scaled down its military presence under pressure from Western allies to end the conflict.
The missile hit in the city's neighbourhood of Breiqa where a military parade was underway by forces loyal to the United Arab Emirates, a member of the Saudi-led coalition that has been fighting the Iran-backed Houthi rebels since 2015 in support of Yemen's internationally recognized government.
The suffering of children caught up in the Yemen conflict has become "simply appalling," according to a UN report. It says thousands of kids have been killed, recruited as soldiers and subjected to devastating violence.
The spokesman of the Saudi-led coalition at war in Yemen against the rebel Houthis was quoted in the state-run Saudi Press Agency as saying the airport in Abha was struck shortly after 9 p.m. local time on Sunday.
Riyadh has accused Iran of supplying the Houthis with the weapon used in the June 13 attack on Abha airport. Tehran and the Houthis deny coalition charges that Iran supplies the Houthis with missiles and drones.
However, the court's decision does not mean Britain must immediately halt arms exports. It does mean that there is a stay on the granting of next arms export licences to Saudi Arabia - Britain's richest Arab ally.
The Saudi-led coalition intervened in Yemen in March 2015 to push back an advance by the Houthis and to restore to power President Abedrabbo Mansour Hadi. Since then, the conflict has killed tens of thousands of people.
Many Yemenis who have fled their homes and farms in and around Hodeidah to head north to the Houthi-held capital Sanaa or to safer areas along the western coast and the southern port city of Aden said that they are struggling to survive.
