SANAA, July 30 (Xinhua) -- Warplanes from the Saudi-led coalition launched a series of airstrikes on a military camp held by Houthi rebels in the Yemeni capital Sanaa late on Monday, residents and Houthi-run media said.

The attack targeted al-Sawad military camp in the southeast of Sanaa.

Windows of sveral houses in the residential neighbourhoods surrounding the camp were partly smashed during the airstrikes, according to the residents.

There was no immediate comment from the coalition, and there were no Houthi reports of casualties from the airstrikes.

The airstrikes came hours after the Houthis claimed responsibility for drone attacks on King Khaled Air Base in the southwest of Saudi Arabia.

Houthis have recently stepped up drone attacks on Saudi Arabia, but most of the drones were intercepted and destroyed by the kingdom's air forces.

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