A suspected US drone strike in Yemen killed two Al-Qaeda militants and destroyed an arms cache on Sunday, a security official and witnesses said.

The raid targeted a house in Wadi Abida, in the central province of Marib, where the two unnamed militants were killed, the official said, requesting anonymity.

He said an arms cache in the house also exploded.

Witnesses said an unmanned drone conducted the air raid, just like in most US air strikes that target Al-Qaeda suspects in the Arabian Peninsula nation, which is home to Al-Qaeda's most active branch.
