An American service member was killed in combat in Afghanistan on New Year's Day, the US military said on Tuesday.
In late November, Nicholson said more USA troops in Afghanistan would be sent to the front lines in 2018 and was frank about the fact it would place them in greater danger.
The US military said two of the injured service members were being treated at a nearby medical facility, but are in stable condition. The others were able to go back into service.
Army Gen. John W. Nicholson Jr., the senior US military commander in Afghanistan, issued a statement expressing condolences for the lost service member.
He added: "At this very hard time our heartfelt sympathies go out to the families and friends of our fallen and wounded brothers".
Sen. Cory Booker, D-N.J., said in a statement that the service member killed is Army Sergeant First Class Mihail Golin of Fort Lee, N.J. He says Golin "served our nation with courage and distinction, and his death is a loss that will be felt across New Jersey".
