2 Americans killed in Afghan attack

kabul mapKabul, Afghanistan (CNN) -- Two Americans -- one a Green Beret -- were killed Monday when an assailant wearing an Afghan National Security Forces uniform opened fire on the group, U.S. and NATO's International Security Assistance Force officials said.

The shootout in eastern Afghanistan didn't last long, as coalition forces "returned fire and killed the attacker," a U.S. official told CNN.



Two Afghan army personnel also were killed, said Gen. Zahir Azimi, an Afghan Defense Ministry spokesman. A U.S. military official told CNN that at least 10 Americans were wounded as well.

The assailant fired at the victims with a truck-mounted machine gun, Azimi said, after a meeting between coalition and Afghan forces at a military base in the Jalrez district of Wardak province, about an hour west of Kabul. Green Berets and Afghan forces are based there, a U.S. official said.

A spokesman for the Taliban, the militant group that once ruled Afghanistan, said the shooter was an Afghan police officer, but it's unclear if that was the case.
