A US service member was killed in action in Afghanistan on Monday, the US military said in a statement.

It gave no further details and withheld the name of the service member until the next of kin were informed.

More than a dozen foreign force members have been killed in Afghanistan in 2019.

About 20,000 foreign troops, most of them American, are in Afghanistan as part of a US-led NATO mission to train, assist and advise Afghan forces. Some US forces carry out counter-terrorism operations against Islamist militant groups.
