U.S. troops mistakenly killed seven Afghan police during a nighttime mission yesterday. The police originally fired on the Americans, thinking they were Taliban fighters; in response, the soldiers opened fire and called in attack aircraft. A spokesman for President Hamid Karzai called the shooting "a tragic incident" sparked by miscommunication.
An investigation into the accident has been opened. Also yesterday, an 8-hour battle in southern Afghanistan ended with the killing of 24 Taliban fighters. The AP reports that over 2,300 people have died in insurgency-related violence this year.
