"U.S. forces conducted airstrikes in Musa Qala today against individuals threatening coalition and Afghan forces," Col. Brian Tribus, a spokesman for U.S. and allied forces in Afghanistan, said without providing further details.

Afghan Army Brig. Gen. Mohammad Rasool Zaizai said Afghan and allied warplanes struck army and police headquarters in the Musa Qala district in northern Helmand province Thursday, likely killing fighters and civilians.

The Republican told reporters that Afghan national forces are fighting bravely, but suffering heavy losses in the field.

American and international troops have already stopped playing a combat role, remaining as trainers for local forces. The international numbers will be reduced further at the end of 2016. But McCain said reductions should be based on conditions on the ground.
