Militants die in Yemen drone strike
The official said the raid targeted a car carrying the militants in the Sawmaa area in the al-Bayda province at the time another car was nearby carrying civilians.
At least six civilians were killed and wounded, the official said.
The deputy governor of al-Bayda was assassinated on Tuesday by suspected al-Qaida militants.
Yemen's branch of al-Qaida, also known as Al-Qaida in the Arabian Peninsula, is considered to be the most dangerous in the world. It overran much of the south in 2011.
Yemen's army, supported by US military experts and drone strikes, pushed them back - but clashes continue.
