Afghan soldier's insider attack wounds 7 American soldiers

The U.S. military says that seven America soldiers were wounded in an insider attack by an Afghan soldier.

A statement on the Resolute Support Twitter feed Saturday says the seven were wounded when an Afghan army soldier opened fire. The attacker was shot and killed when soldiers returned fire. One Afghan soldier was wounded. There were no U.S. fatalities.

A Taliban spokesman praised the attack but did not claim responsibility.

Abdul Qahar Araam, spokesman for the 209th Army corps, confirmed Saturday that an insider attack took place at a camp in Mazar-e Sharif. 

Last week three U.S. soldiers were killed by an Afghan soldier in eastern Nangarhar province.

On Thursday, the Pentagon said it will send nearly 4,000 additional troops to Afghanistan in order to stop Taliban advances.
