(CNN) -- A suspected U.S. drone strike in northwestern Pakistan has killed at least four people, a Pakistani intelligence source said.
The attack wounded at least five people, according to the source, who asked not to be named because he is not authorized to speak to the news media.
The strike happened in the area of Machi Khel in North Waziristan, a part of northwestern Pakistan that has been the scene of clashes between Taliban militants and the Pakistani military.
The U.S. military is believed to have carried out several drone strikes in the region, as well.
