Yemeni drone strike kills four

At least four people were killed on Friday in a presumed U.S. drone strike in Yemen's central al-Bayda province, a local government source said.

The strike took place in the district of Rada'a and killed the local al Qaeda leader there and three others, the government source told Reuters. Tribal sources put the death toll at five.

"The drone targeted a place where they were meeting," a local source said.

Drone attacks have killed at least 40 people in Yemen since late July.
