Four suspected Al-Qaeda members were killed in drone strikes in central Yemen likely carried out by US forces, a security source said on Sunday.
The source, asking not to be identified, said three "armed fighters of Al-Qaeda" died when their vehicle was struck on Saturday in the Sawmaa region of Al-Bayda province.
A drone strike on Friday killed a local military instructor for Al-Qaeda in the same province, he said.
The United States, which considers Al-Qaeda's Yemen-based franchise, Al-Qaeda in the Arabian Peninsula (AQAP), to be its most dangerous, is the only force operating drones over Yemen.
But it only sporadically reports on a long-running bombing campaign against AQAP.
Al-Qaeda and the Islamic State jihadist group have exploited a power vacuum created by the two-year-old conflict in Yemen between the government and Houthi rebels, especially in the country's south and southeast.
