Afghan officials say a NATO airstrike has killed four Afghan police officers and wounded two others in the country's east.

The governor of Nuristan province, Jamaluddin Badar, said Monday coalition forces also detained 12 police officers after NATO aircraft bombed the police post in the Wama district.

Badar said the strike was based on wrong intelligence. He said the officers were wearing police uniforms and an Afghan flag was flying at the post when it was attacked.

Nuristan's remote, mountainous Wama district borders Pakistan and has been the scene of insurgency-related violence.

NATO says it is “aware” of the statements by Afghan officials alleging friendly fire and is investigating the incident.

Also Monday, the British Broadcasting Corporation called on NATO forces in Afghanistan to investigate the death of one of its reporters during a Taliban attack last week in the southern province of Uruzgan.

Ahmed Omed Khpulwak, a reporter for the BBC and the Pajhwok Afghan news agency, and 18 others were killed on July 21, when a group of suicide bombers and gunmen attacked several government buildings in Uruzgan's capital, Tarin Kot. Afghan forces repelled the assault with the help of the international coalition.

The BBC said Monday that “conflicting reports” about who shot and killed Khpulwak prompted them to ask the coalition for a probe into the 25-year-old reporter's death.
