A U.S. service member was killed in Afghanistan Thursday.

The service member was assigned to the NATO Resolute Support mission in the country.

This incident is under investigation, Resolute Support said in a press release Thursday morning.

"We mourn and honor the sacrifice of our service member,” said Resolute Support and United States Forces – Afghanistan Commanding Gen. Scott Miller. “We remain committed.”

In accordance with the U.S. Department of Defense’s policy regarding fallen service members, the individual’s name is being withheld until 24 hours after their next of kin has been notified.

Resolute Support did not immediately respond to Military Times' questions regarding the service member’s cause of death and location within Afghanistan at time of death.

According to the Defense Casualty Analysis System, eight U.S. military members have been killed and 76 wounded in Afghanistan so far in 2018.
