Ten people were injured in two explosives-laden drone attacks at King Abdullah airport in the southern Saudi city of Jizan late on Friday and early on Saturday.
There was no immediate claim of responsibility by Iran-backed Houthis, who regularly launches drone and missile attacks targeting the gulf kingdom.
The latest attack comes as Saudi Arabia and Iran are engaged in talks to address tensions in their relations that have especially prevalent since they broke diplomatic ties five years ago.
Iran’s foreign minister Hossein Amir-Abdollahian in a visit to Lebanon on Thursday and Friday emphasized that the talks are on the right track and highlighted their importance for regional security.
Six Saudis, three Bangladeshi nationals and one Sudanese were injured in the first attack, Saudi state media said, citing a coalition spokesman. Some of the airport's facade windows were shattered in the attack, the spokesman said.
A second explosives-laden drone was intercepted early on Saturday, the coalition said, without giving details on any injuries or damages.
The military coalition intervened in Yemen in 2015, backing forces of the ousted government of President Abdrabbuh Mansur Hadi and fighting the Iran-aligned Houthi group.
