At least four people were killed in Miranshah when a US drone was fired in North Waziristan, officials said Sunday.
The strike came at about 10: 50 a.m. 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.
Two people were killed on the spot while two others killed afterwards. Identities of the killed are not immediately known.
Earlier, at least six people were killed in a US drone strike on a suspected militant compound in North Waziristan on September 22, officials said.
US drone attacks are deeply unpopular in Pakistan, but Washington views them as a vital tool in the fight against Taliban and Al-Qaeda militants in the lawless tribal areas along the border with Afghanistan.
Sunday's U.S. drone strike in North Waziristan is the 21st of its kind in Pakistan in 2013. According to Xinhua's tally, at least 117 people have reportedly been killed in such strikes since the start of the year.
