ISLAMABAD, Dec. 21 (Xinhua) -- At least four people were killed and many others were injured on Friday afternoon when a U.S. drone launched a strike in Pakistan's northwestern tribal region of North Waziristan, local media reported.
According to the reports, the pilotless plane fired two missiles at a house in Hesokhel village of Mir Ali, a famous district of North Waziristan.
The missile strike completely destroyed the house and killed four people present in the building.
Soon after the incident, local people rushed to the site and started rescue work to take the dead bodies and injured out of the debris.
The injured were being shifted to the local hospital for treatment but local rescuers were unable to tell the number of wounded people.
Earlier on Thursday night, a U.S. unmanned aircraft, which was reportedly being used to target militants' hideouts, crashed in Pakistan's northwestern tribal region of South Waziristan, the neighboring area of North Waziristan.
According to the reports, the pilotless plane crashed in the Wana district of South Waziristan, a restive tribal region bordering Afghanistan.
Local media quoting official sources reported that the U.S. drone might had come to attack some target but crashed apparently due to some technical fault.
U.S.-led NATO forces fighting in Afghanistan believed that Pakistan's bordering areas especially North Waziristan and South Waziristan are the safe havens for the militants who allegedly attack NATO forces in Afghanistan.
Pakistan, on a number of occasions, protested and expressed its reservations over such strikes, terming them the violation of its sovereignty but U.S. considered it an effective strategy to eliminate militants hiding in hilly areas.
The Friday attack is the 39th of its kind (counted on daily basis) in Pakistan during 2012, killing at least 273 people and injuring hundreds of others.
On Dec. 9, at least four people were killed when a U.S. drone launched a strike firing four missiles at a house in North Waziristan.
Earlier on Dec. 1, U.S. drone attacked a suspected house in South Waziristan killing at least four people including an al- Qaeda leader Abdul Rehman Azman, a Yemeni national believed to be one of the close friends of the former al-Qaeda head Osama bin Laden.
