Nine policemen were killed in Afghanistan Sunday in international military air strikes called in when police and troops clashed after mistaking each other for Taliban, authorities said. The fighting erupted at about 1:30 am when Afghan and international soldiers moved into a district without informing police, who thought they were militants, the deputy governor of southwestern Farah province said. "An engagement took place, each side thinking the other was the Taliban," Mohammad Younus Rasouli told Agencies. The troops called for air support and military attack aircraft arrived and bombed a police post, he said. "Nine police were killed and five wounded," he said.
