In reply to Bob_the_Builder: I threw that Italian page through a translator.
Doesn't read very well. But essentially they crossed a rope the sherpas were moving gear up after the sherpas asked them not to. The sherpas are claiming they were hit by falling ice, Ueli and co are claiming that the sherpas got jealous they were moving faster and unroped.
After an argument and a bit of a fight at altitude, they went down to a camp, where over 100 sherpas attacked the climbers and a load of westerners intervened. Ueli and co left the normal route and forged a new descent route to go and hide as some serious death threats have been made.
Apparently no sherpa has been injured.
