Man Believed to Be Afghan Police Officer Kills Two NATO Troops, Officials Say

From FoxNews.com:

URGENT: A man believed to be a member of the Afghan Local Police shot and killed two NATO troops on Saturday, the coalition said in a statement.

The "insider" attack on the two soldiers occurred in Helmand province in southern Afghanistan. NATO reported that another service member returned fire, killing the gunman.

The attack is under investigation.

The rising number of insider attacks is complicating plans to train Afghan forces so that most foreign troops can withdraw from the country by the end of 2014.

So far this year, 47 international service members have died at the hands of Afghan soldiers or policemen or insurgents wearing their uniforms. There were at least 12 such attacks in August alone, resulting in 15 deaths.
