The drone targeted a vehicle in the village of Al-Qatan, in the province of Hadramawt, where Al-Qaeda in the Arabian Peninsula (AQAP) remains active despite Yemeni military operations and US drone strikes targeting its leaders.
The US military operates all the unmanned drones flying over Yemen, but US officials rarely discuss the covert campaign.
Yemen is the ancestral home of Osama bin Laden and the home base of AQAP, which the United States views as the global jihadist network's most dangerous franchise.
