1 NATO soldier killed in Afghanistan

A NATO soldier was killed and three wounded during an operation in eastern Afghanistan, the U.S. military said Friday.

Four wounded soldiers were evacuated to a medical facility after the operation Thursday evening, where one died of his wounds, the military said. The three others are in stable condition.

The military did not specify the soldiers' nationalities or where the operation occurred. The majority of soldiers operating in eastern Afghanistan are American.

The death brings to at least 22 the number of U.S. or NATO soldiers who have died in Afghanistan this year, including at least 11 U.S. soldiers and five British.
