Six suspected militants were killed and two others wounded in a US drone strike in the remote Shawal Valley in the North Waziristan tribal region late Saturday afternoon, sources said.
These sources said that the drone fired two missiles into a compound in the valley close to the Pakistan-Afghanistan border, killing six militants. Most of those killed were foreigners, they added.
The number of casualties was set to rise, the sources said, wishing not to be identified.
Dattakhel and Shawal are by far the two major areas where the military is concentrating on air power to soften up the area infested by local and foreign militants, who fled Operation Zarb-i-Azb in North Waziristan.
