Two helicopters collided in Nepal's Mount Everest region, killing at least one person and injuring two others, according to local officials.
The collision occurred on Tuesday as both aircraft were attempting to land just below Everest base camp — the world's highest mountain measured from sea level.
Video posted online showed more than a dozen people running for cover as the two helicopters crashed to the ground after the collision.
Authorities confirmed that a 47-year-old Indian national was killed. A New Zealand national and a Nepali pilot were injured. It was not immediately clear how many people were aboard the two helicopters.
The accident took place in Pheriche village, at an altitude of 4,200 meters (13,780 feet).
The Everest region is hard to reach overland because there are no roads. Helicopters are commonly used to evacuate trekkers and guides forced to cut short their journeys due to illness or exhaustion. Temperatures in the mountains remain below freezing.
Last week, a fire broke out at a hotel along the route to Everest base camp. Heavy snowfall hampered efforts to extinguish the blaze. No casualties were reported in the fire.
