Panetta: No pattern of Afghan soldier attacks on NATO troops

A man who was apparently a local policeman allegedly killed an American in eastern Afghanistan on Monday, and two British troops were shot and killed in southern Afghanistan, according to CNN.

U.S. commander in Afghanistan Gen. John Allen warned Monday that U.S. and NATO troops will continue to be at risk of being killed by their Afghan counterparts throughout the conclusion of the war.

The green-on-blue violence against American soldiers is simply “a characteristic of counterinsurgency [operations],” Allen told reporters during a briefing at the Pentagon.

Allen noted that the majority of the attacks by Afghan soldiers are not due to Taliban infiltration, but rather the result of soldiers who become “self-radicalized,” and that many have also attacked fellow Afghan troops.

So far in 2012, 16 of the 93 NATO troops have been killed in “green-on-blue” attacks, according to CNN.
