The strike took place in Tabbi village, 5km north of Miranshah, the main town in North Waziristan.
“US drones fired four missiles on a militant compound, killing three rebels,” a senior security official told AFP on condition of anonymity.
Sunday’s U.S. drone strike is the 38th of its kind (counted on daily basis) in Pakistan in 2012. At least 269 people have been killed in such strikes since this year.
Pakistan has long been opposing US drone attacks in its tribal belt that borders Afghanistan, where US and its ally forces are station.
Tabbi village, which is very close to the Afghan border, is said to be a hideout for militants belonging to several groups including those from Hafiz Gul Bahadur and the Haqqani network.
The al-Qaeda-linked Haqqani network, blamed for some of the deadliest attacks in Afghanistan, is one of the thorniest issues between Islamabad and Washington.
Washington has long demanded that Pakistan take action against the Haqqanis, whom the United States accused of attacking the US embassy in Kabul in September last year.
This comes as Abu Zaid was killed in the drone strike on a hideout in Pakistan’s North Waziristan, one of the tribal regions near the border with Afghanistan, early on Thursday, the sources said. Zaid had just moved to the hideout a few days ago, they said.
