Authorities are currently investigating the cause of the crash, which occurred in the Shah Wali Kot district of southern Kandahar province.
"The crash resulted in the deaths of four International Security Assistance Force service members, three United States Forces-Afghanistan service members, three members of the Afghan National Security Forces, and one Afghan civilian interpreter," the International Security Assistance Force said.
The Taliban have claimed responsibility for the attack, but the BBC reported that its claims could not be verified.
According to the AFP, because the NATO mission relies heavily on air transport, helicopter crashes are frequent in Afghanistan.
Last year, an American Chinook was shot down by the Taliban near Kabul. The attack killed eight Afghans, and 30 Americans, including 22 Navy SEALs from SEAL Team 6, the unit that killed Osama bin Laden last May.
