A US service member was killed in action on Oct. 4, 2018, Operation Resolute Support said in a statement.

The incident is under investigation, officials said.

"We mourn and honor the sacrifice of our service member," Gen. Scott Miller, the commander of US and Resolute Support forces in Afghanistan, said. "We remain committed."

The person's name is being withheld pending notification of the person's family.


Oct. 4, 2018's death is believed to mark the eighth this year for US troops in Afghanistan.

In early September 2018, a US service member was killed in a noncombat incident, and one day prior another died in an insider attack. Another apparent insider attack in July 2018 claimed the life of a 20-year-old Army soldier.

Casualties among Afghan forces are on the rise. About 500 Afghan troops were reportedly killed in September 2018.

The latest American death comes just ahead of the 17th anniversary of the start of the war in Afghanistan, which began October 7, 2001, in the wake of the 9/11 terrorist attacks. Children born after the deadly attacks are now old enough to enlist to fight in the war, a bloody stalemate with no clear end in sight.

Army Gen. Joseph Votel, the commander of US Central Command, told reporters that the Taliban could seize the initiative in short campaigns but couldn't sufficiently hold territory to secure victory.
