The NATO alliance in Afghanistan says a civilian helicopter has crashed during takeoff in the country's south, killing 16 people.
NATO officials say a Russian-built (Mi-8) helicopter crashed Sunday while taking off from Kandahar's main air base. Reports from the area say 20 people were on board. Kandahar Air Field is NATO's largest base in southern Afghanistan.
Separately, a U.S. military helicopter in the northeast made an emergency landing in Kunar province.
A U.S. military spokeswoman, Lt. Commander Christine Sidenstricker said no enemy fire was reported near either incident.
Last week, a helicopter crashed in Helmand province, killing all six civilian contractors on board and a child on the ground.
Afghan officials said the aircraft may have been shot down by insurgents. But NATO commanders say the cause of the crash is not clear and under investigation.
