Nepal changes Everest climbing route

The route used by mountaineers to scale Mount Everest is to be changed amid fears of an increased avalanche risk.
Nepal will change the path next month after a deadly collapse in 2014 killed 16 Sherpa guides - the worst single loss of life in expedition history.
The current route up the mountain has been in use since the 1990s.
Mountaineers will now take a more central route after Base Camp, avoiding the left side of the Khumbu Icefall, where last year's accident occurred.
The fatal avalanche last year triggered a boycott by Sherpa climbers who demanded better wages and conditions. Their protest at Base Camp led to the cancellation of all expeditions to Everest.
The central route up the mountain immediately after Base Camp is not actually new. It was the path used by mountaineers more than two decades ago.
But in the 1990s, the route was changed to run up what is known as the "west shoulder" because it was shorter and easier to climb, even for inexperienced mountaineers.

Some 250 people in total have died trying to climb Mount Everest since it was first scaled in 1953.
