SANAA, Yemen (AP) -- Yemeni security and military officials say a suspected U.S. drone has killed two militants in a town in the center of the country.

The officials said the Monday attack targeted the two men as they were riding a motorbike outside Radda in Bayda province. The officials said the two men were suspected of belonging to al-Qaida, whose Yemeni branch Washington considers the terror group's most dangerous offshoot.

The officials spoke on condition of anonymity because they were not authorized to speak to the media. The U.S has regularly used drone strikes in Yemen to go after the group's members, while government troops are also confronting them in various parts of the country.
