9 Afghan police officers killed in mistaken coalition air strike

KABUL, Afghanistan (CNN) - A misunderstanding between local police and coalition forces led to an air strike in southwestern Afghanistan Sunday that left nine police officers dead, a defense ministry official said.

The nine officers were killed after they were mistaken for Taliban militants by coalition forces, said Gen. Mohammad Zahir Azimi.

The aerial attack took place in the Anar Derah district in Farah province. It was conducted by U.S. soldiers along with troops from the Afghan army, Azimi said.

He did not have any further information about the attack.
