Nepal earthquake: Avalanche 'was like a tsunami of ice'
Jost Kobusch is a 22-year-old German climber who filmed the first avalanche video at Everest base camp after the devastating earthquake that hit Nepal last Saturday.
The video was widely shared on social media.
The BBC's Jonathan Head interviewed Mr Kobusch in Lukla just after he had returned back from the base camp, and he described what he saw.
