DUBAI (Reuters) - The Saudi-led coalition fighting the Houthi group in Yemen said it destroyed an armed drone fired towards the kingdom on Friday, part of an attack the Houthis claimed to have launched into southern Saudi Arabia at dawn.


The Houthis have recently stepped up cross-border drone and missile attacks on Saudi cities, mostly targeting the southern part of the kingdom. The coalition says it intercepts most attacks.


The Houthis fired the intercepted drone towards Khamis Mushait near the Yemen border on Friday, Saudi state news agency SPA said.


Houthi military spokesman Yahya Sarea said in a Twitter post that three drones had hit Abha International Airport and King Khalid Air Base, in the Khamis Mushait area.


Yemen's Iran-aligned Houthi forces on Thursday said they fired a missile and hit a Saudi Aramco facility in the Red Sea city of Jeddah, but there has been no confirmation from Saudi authorities.


The United States and United Nations have renewed peace efforts as fighting has also intensified in Yemen's gas-rich Marib region.


On Tuesday, the U.S. Treasury Department imposed new sanctions on two Houthi military leaders.


The conflict is widely seen as a proxy war between Saudi Arabia and Iran. The Houthis deny being puppets of Tehran and say they are fighting a corrupt system.
