A senior Pakistan Taleban commander is believed to have been killed in a United States drone strike, the first since President Barack Obama announced tighter regulations on their use.
Two missiles were reported to have been fired from an unmanned drone, hitting a house in a village near Miran Shah in North Waziristan.
The operation will further complicate the debate over the use of drones, and will present an immediate challenge for Pakistan's Prime Minister-elect, Nawaz Sharif, whose party campaigned against the programme in elections this month.
Pakistani intelligence officials told Reuters that among up to seven people killed was Wali-ur-Rehman, considered number two in the Pakistan Taleban.
However, there was no immediate independent verification. The Taleban denied that he was dead.
