ADEN: A drone strike in Yemen’s southeastern Hadramawt province killed three Al-Qaeda suspects on Tuesday, local authority officials said. The three men were traveling in the Wadi Houaira area when a missile hit their vehicle, the sources said.

The US is the only country that operates drones in the region.

The number of victims from the drone strikes in Yemen remains unclear and estimates vary widely.

According to the Washington-based New America Foundation, a think tank that tracks and vets drone activity, 93 strikes in Yemen since 2002 have killed 684 to 891 people including between 64 and 66 civilians.

Yemen is the ancestral home of Al-Qaeda founder Osama Bin Laden and the home base of Al-Qaeda in the Arabian Peninsula.
