An official says foreign troops called in airstrikes during an apparently mistaken clash with Afghan police, killing nine police officers and wounding five others in the country's west. The deputy governor of Farah province Younus Rasuli says a convoy of foreign forces showed up at Anar Derah district. He says the foreign troops did not inform local Afghan officials they were coming, and the police thought they were enemy fighters, according to a report of the Associated Press. Rasuli says the two sides fought from about midnight till 4 a.m. Sunday, and foreign forces called in air strikes. Both NATO and U.S. coalition officials say they are looking into the reports.
