Yemeni security officials say Saudi-led airstrikes have for the first time hit the rebel-held General Army Command building in the center of the capital, Sanaa.

They say strikes also hit rebel areas outside Sanaa and in the Arish part of the southern city of Aden on Tuesday, as well as several locations in the city of Taiz, including the command center of the 25th Mechanized Brigade.

They say airstrikes targeted several gatherings of the rebels, known as Houthis, in the city of Dhale, as well as sites in their northern stronghold, Saada.

The officials, who spoke on condition of anonymity because they weren't authorized to brief reporters, said that three civilians died in the Sanaa attack and nearby homes were damaged.
