Three climbers from Latvia who fell near a risky pass on Denali — North America's highest peak — have died, a Latvian mountaineering group said Friday.

A fourth member from the mountaineering expedition was rescued in a critical condition.

Denali, also known as Mount McKinley, stands at a height of 20,310 feet (6,190 meters) above sea level in the US state of Alaska.

What do we know?

A seven-person group was on the popular West Buttress route to the summit when four of the climbers fell during their ascent near Denali Pass on Wednesday, the Denali National Park and Preserve said.
