Three U.S. service members were killed and three others were wounded by an improvised explosive device in southern Afghanistan, according to the NATO-led training mission in that country.
The incident took place on Nov. 27, Resolute Support, the official name of the NATO mission, said in a statement. One American contractor was also wounded.
“The wounded service members and contractor were evacuated and are receiving medical care,” Resolute Support said.
No other details about the deadly incident were available.
Five service members so far have died in Afghanistan in November — the deadliest month for U.S. forces this year.
