A US drone strike has killed six militants in Pakistan's lawless tribal belt along the Afghan border, local security officials said.
Four missiles hit a house used by militants in Dashgah village near Datta Khel town, some 45km west of Miranshah, the main town in North Waziristan tribal district, in the attack.
"Two US drones fired four missiles and destroyed the house. Six militants were killed in this attack," a Pakistani security official based in Peshawar said on condition of anonymity.
Two intelligence officials in Miranshah also confirmed the attack and the death toll.
"All of them were militants attached to the Haqqani group," one intelligence official said.
The second intelligence official said that initial reports suggested the dead were Uzbek militants from Afghanistan.
Under US pressure to crack down on Islamist havens, Pakistan has stepped up military operations against largely homegrown militants in the area.
But commanders have so far avoided a major offensive in North Waziristan, arguing that gains elsewhere need to be consolidated to prevent their troops from being stretched too thin.
