Pakistani officials say a suspected US missile strike in northwest Pakistan has killed four militants.
Three intelligence officials said the Friday overnight attack targeted two vehicles in the Kurram tribal region.
One of the officials said on Saturday the slain men were from Taliban's Haqqani network which is blamed for launching attacks across border against the American and Nato forces.
The officials spoke on condition of anonymity because they were not authorised to talk to the media.
Although the CIA has repeatedly targeted militant positions in Pakistan's tribal regions, such strikes in Kurram are rare.
