The Saudi-led Arab coalition accused on Monday the Iran-backed Houthi militias in Yemen of using government ministry buildings to launch military attacks.

"We have destroyed a communication system used to operate drone control stations," the coalition was quoted as saying by the official Saudi news agency SPA.

"The Houthis are using the Ministry of Telecommunications and Information Technology in Sanaa for hostile operations," it added.

The coalition said the raids were in response to a drone attack Thursday on Saudi Arabia's Abha International Airport near the border which left 12 injured by falling debris after the Saudi military blew up the bomb-laden projectile.

The coalition had warned it would strike positions from which the Houthis launch drones in Sanaa and asked civilians to leave civilian areas used for military purposes.

"The Houthis are using state ministries to launch hostile operations," the coalition said.
