NATO secretary-general Jens Stoltenberg has condemned Iran's missile strike against U.S. forces in Iraq, while a NATO official says there were no casualties among the military alliance's personnel in the country.
The Iraqi mission consists of several hundred staff from allied nations and non-NATO countries.
In a message to The Associated Press, the NATO official who was not authorized to speak publicly said they were "keeping the situation under close review."
Meanwhile, in a message posted on Twitter, Stoltenberg urged Iran to refrain from further violence.
