A U.S. service member was killed late Friday in a helicopter crash in Afghanistan that left six other crew members injured, NATO said in a statement.

The crash occurred in Afghanistan's eastern Logar province and "was not the result of enemy action," according to the statement. A spokesperson for the Taliban had previously claimed responsibility for the crash.

"We are deeply saddened by the loss of our comrade," said Gen. John Nicholson, the top U.S. commander in Afghanistan. "On behalf of Resolute Support, our heartfelt sympathies go out to the families and friends of our fallen comrade and those injured in this unfortunate event."

A spokesperson for the provincial governor in Logar told the Associated Press earlier Friday the helicopter had been forced to make an emergency landing while transporting troops to the Karwar district for a night raid.

However, Resolute Support said it is still investigating the circumstances surrounding the crash and will release further details "as appropriate."
