A U.S. drone aircraft fired a missile on the Pakistani region of North Waziristan on the Afghan border, killing five suspected fighters, security officials said on Saturday.
The nationality and identity of the foreigners was not known, an official said.
The latest attack, the 12th this month according to a Reuters tally, happened 20 km (12 miles) west of Miranshah, the main town in North Waziristan, late on Friday.
"The missile struck a compound used by militants and we have reports of five dead. Two of them were foreigners," said a security official in the region, who declined to be identified.
The drone strikes are a source of friction with Pakistan who sees the attempts as a "violation of sovereignty."
Pakistan says the drone aircraft attacks complicates its efforts against Taliban by inflaming public anger because of civilian casualties.
Pakistan wants the United States to supply it with armed drones so it can do the job itself but the United States has only offered surveillance drones.
The latest strike came after an international meeting on Afghanistan in London where the Afghan government invited the Taliban to a peace council.
The United States carried out 51 drone strikes in Pakistan last year compared with 32 in 2008, according to a Reuters tally.
