An American soldier and an American contractor were killed Saturday night when an Afghan soldier opened fire on U.S. troops at a checkpoint in eastern Afghanistan.

The recent attacks bring the death toll of American troops to 2,000 since the start of the war 11 years ago, according to a count kept by the Associated Press. Afghan soldiers and policemen have gunned down more than 50 foreign troops so far this year.

The attacks are taking a toll on the partnership between international and Afghan forces. The U.S. military is now restricting operations with small-sized Afghan units.

It's not clear if the shooter in the latest attack was killed. The deaths are under investigation.
