ISLAMABAD , Pakistan ( CNN ) -- A suspected U.S. missile from an unmanned drone killed three people Saturday in Pakistan 's tribal region , according to a Pakistani military source and a North Waziristan official . Young Pakistanis look at a house after a missile hit it in the tribal region of North Waziristan last month . The strike hit a village near Miran Shah , in North Waziristan , the military source and Muhammad Nasim , a North Waziristan political official , said . The military source asked not to be identified because he is not authorized to speak to the media . This is the latest in a series of deadly missile strikes in Pakistan 's border region over the past two months . Pakistan has repeatedly blamed the United States and condemned the strikes , saying they cost lives , violate the nation 's sovereignty and undermine public support for its counterterrorism efforts . The U.S. government has not acknowledged hitting targets within Pakistan , an ally in the war on al Qaeda launched after the September 11 , 2001 , attacks on New York and Washington . The U.S-led coalition and NATO -- based in Afghanistan -- have been seeking a way to effectively battle Taliban and al Qaeda militants who they believe are launching attacks from Pakistan 's swath of tribal areas along the border . They have become frustrated with Islamabad over the years , saying it is not being active enough against militants -- a claim Pakistan denies . A week ago Saturday , two missiles , also believed fired by a U.S . Predator drone , hit a house in the North Waziristan region and killed at least four people and wounded six others , a local official said . North Waziristan is one of seven districts within Pakistan 's ungoverned tribal region along the Afghanistan border . Pakistan 's Foreign Ministry recently has summoned U.S . Ambassador Anne Patterson to lodge formal protests . On November 20 , the ministry lodged a protest with Patterson against a strike in the Bannu region of Pakistan 's North West Frontier Province that left five dead and seven wounded and was deeper inside Pakistani territory than previous attacks . In October , the Foreign Ministry summoned Patterson and said strikes should be stopped immediately . At the time , a missile strike from a suspected U.S. drone on a compound in South Waziristan killed 20 people . The United States is the only country operating in the region known have the capability to launch missiles from drones , which are controlled remotely . CNN 's Reza Sayah contributed to this report .
