mount everest (Nepal) (AFP) - AFP Nepal bureau chief Ammu Kannampilly was at Everest base camp on Saturday when an avalanche cascaded down the mountain, flattening everything in its path.Eighteen people are so far known to have died in the tragedy which comes barely a year after the death of 16 sherpa guides in an avalanche that had been the worst disaster in Everest's history.Here she talks to survivors about their experiences when part of the camp was obliterated, and how they coped with the aftermath: - 'Message from the mountain' - Still incredulous at surviving being flattened by a massive wall of snow, George Foulsham says the latest disaster on Everest felt like a message from the mountain that "it's not meant to be climbed for now". Like many of the climbers, Foulsham had returned to base camp for a second shot at the summit of the world's highest mountain after last year's climbing season was cancelled for the first time ever.Speaking at base camp, the 38-year-old marine biologist recounted the moment that he was knocked off his feet by what he called "a 50-storey building of white"."I ran and it just flattened me.
