Nine people were injured following an attack by the Houthi militia targeting Saudi Arabia’s Abha International Airport on Tuesday, the Arab Coalition said.

“The terrorist attack on Abha airport… led to the injury of nine civilians, including eight Saudi citizens and one carrying an Indian passport,” coalition spokesman Colonel Turki al-Maliki said in a statement, adding that they were all in stable condition.

He stated that the attack took place at 12:35 am local time.

The Iran-backed Houthis have stepped up attacks on neighboring Saudi Arabia in recent weeks. On June 23, the militia had also targeted Abha airport, killing one and injuring seven others.
