At least four people have been killed in a non-UN-sanctioned drone strike in Pakistan's northwestern tribal region of South Waziristan.
The attack took place on Friday when the drone fired two deadly missiles at a house in Sheen Warsak area, a Press TV correspondent reported.
Washington claims the attacks target al-Qaeda-linked and pro-Taliban militants in Pakistan's northwestern tribal regions bordering Afghanistan. However, locals say the strikes kill civilians.
A recent study conducted by the London-based Bureau of Investigative Journalism has revealed that at least 2,200 people, including up to 168 children, have lost their lives since drone strikes began under George W. Bush in 2004.
Islamabad has repeatedly condemned the strikes as a violation of its sovereignty, asserting that such attacks have proved counterproductive in the so-called war against terrorism.
