At least four people were killed in a U.S. drone strike launched in Pakistan's northwest tribal area of North Waziristan on Sunday morning.
The strike came at about 10: 50 a.m. local time when U.S. unmanned aircraft fired two missiles at a house suspected of being a militant hideout in the Dargah Mandi area of Miranshah in North Waziristan.
Sunday's U.S. drone strike in North Waziristan is the 21st of its kind in Pakistan in 2013.
Nearly 117 people have reportedly been killed in such strikes since the start of the year.
