Three missiles were fired at a house in the Datta Khel area on Wednesday evening, killing five, including the foreigners, an official said.

The foreigners were said to be from Turkmenistan, and members of the Islamic Movement of Uzbekistan (IMU).

Minutes later, a car parked outside the house was hit, killing three others.

Local tribesmen said that Taliban militants took away the dead and injured.

Apart from the foreigners, the dead are said to be Taliban militants loyal to Hafiz Gul Bahadur - the group's main commander in the area.

Correspondents say Datta Khel, about 30km (19 miles) from North Waziristan main town of Miranshah, is a safe haven for al-Qaeda.
