(AP) A man in an Afghan uniform shot and killed three American troops Friday morning in southern Afghanistan, the U.S. military command said, in the third attack on coalition forces by their Afghan counterparts in a week. The Taliban claimed the shooter joined the insurgency after the attack.
So far this year, at least 21 similar attacks -- in which Afghan forces or insurgents disguised in Afghan uniforms have turned their guns on international troops -- have killed 30 coalition service members, according to an Associated Press tally.
Friday's shooting took place in Sangin district of Helmand province, said U.S. military spokeswoman Maj. Lori Hodge. She gave no further details and said the military were investigating.
