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.

International mountain guide Alan Hinkes described the old route through the Khumbu Icefall, where last year's accident occurred.

"There are big bits of ice faces you've got to climb that could be the size of a couple of houses or a small block of flats," Mr Hinkes said.
