Saudi-led coalition warplanes bombed rebel troop headquarters in the Yemeni capital on Wednesday in strikes that killed "at least 15" people, witnesses and medical sources said.
The jets targeted the special forces command headquarters in southern Sanaa, as well as an arms depot in Fajj Attan, a neighbourhood overlooking the capital, residents said.
Medics told AFP that the raids had inflicted "dozens" of casualties, without providing a specific toll.
One medical source at Sanaa's Sabeen Hospital said the facility had received "at least 15 dead and dozens wounded", without specifying if the casualties included civilians.
A coalition led by Riyadh launched air strikes in Yemen in March against Shia Houthi rebels and allied forces loyal to former leader Ali Abdullah Saleh, in a bid to restore UN-backed President Abd-Rabbou Mansour Hadi to power.
The United Nations says that almost 2,000 people have been killed and more than half a million displaced in the conflict since March.
