Monday's incident in Wardak province appears to be the latest in a series of insider attacks against foreign and Afghan forces. It comes a day after a deadline given by Afghans for US Special Forces to withdraw from the province, Fox News reported.
Deputy provincial Police Chief Abdul Razaq Koraishi said three Afghan officers were killed. A coalition military official said two US forces were killed. The official spoke on condition of anonymity to disclose information pending an official statement.
The majority of US troops in Wardak are special operations forces.
