SANAA, July 8 (Xinhua) -- Yemen's Houthi rebels said they attacked airport and Tahamah power plant in Saudi Arabia's southern city of Abha on Monday night, using bomb-laden drones, the rebels' al-Masirah satellite TV channel reported.

The drones hit the targets in the airport and the power plant, the television said, citing a statement by the group's military spokesman.

The attacks forced air traffic to temporarily halt, it added.

However, Saudi Arabia said "it intercepted what appeared like a drone over Abha airport," adding that its airport functions normally, according to Saudi-owned Al Arabiya television.

Iran-allied Yemeni rebels have recently stepped up missile and drone attacks on Saudi Arabia. Most of the attacks were intercepted by the kingdom's air forces.

Saudi Arabia has been leading an Arab military coalition against the Iran-allied Houthi rebels in Yemen for more than four years in support of the exiled internationally recognized government of Yemeni President Abd-Rabbu Mansour Hadi.
