Again: Afghan soldier kills two American soldiers, two Afghans

Saturday’s shooting took place at an Afghan army checkpoint just outside a joint U.S.-Afghan base in Wardak province, said Shahidullah Shahid, a provincial government spokesman.

“Initial reports indicate that a misunderstanding happened between Afghan army soldiers and American soldiers,” Shahid said. He said investigators had been sent to the site to try to figure out what happened.

An Afghan official speaking on condition of anonymity said three Afghan soldiers were killed in the clash. It was not clear if the assailant was among the dead.
