A US drone strike on Friday killed three suspected militants in a compound in Pakistan's northwestern tribal area of Kurram, officials said.
According to the security officials, two missiles were fired near the Pakistan-Afghanistan border from an unmanned aerial vehicle, killing three suspected militants and injuring another, Dawn online reported.
The identities of those killed and wounded remained unclear.
US drone attacks inside Pakistan have become infrequent over the past few years. In its last high-profile attack inside Pakistan, the US had in May 2016 killed Afghan Taliban leader Mullah Akhtar Mansour in Balochistan.
In June, a drone strike had killed a commander of the deadly Haqqani network in Khyber Pakhtunkhwa's Hangu district.
Haqqani network leader Abubakar and his partner were killed when a drone fired two missiles at his house in Speen Tal area of Hangu.
In April, a suspected US drone strike had killed several Taliban militants in North Waziristan close to the Afghanistan border.
