In one of the strikes, the drone fired three missiles at a gathering of suspected al-Qaeda militants in Riyan Airport of Hadhramaut’s provincial capital city of al-Mukalla, located about 800 kilometers (497 miles) southeast of the capital, Sana’a, on Saturday, leaving five people dead, Arabic-language al-Bawaba news website reported.
Reports say militants have reportedly been holed up in the airport for months.
The development came hours after another remote-controlled US aircraft targeted four suspected al-Qaeda-linked militants as they were travelling in a car in the province of Jawf, killing all of them.
Washington has been conducting targeted killings through the remotely-controlled armed drones in Afghanistan, Pakistan, Somalia and Yemen.
The US says the airstrikes target members of al-Qaeda and other militants, but according to local officials and witnesses, civilians have in most cases been the victims of the attacks.
