Two more climbers killed on Mont Blanc A group of climbers from Poland and Spain were being treated in hospital on Sunday after becoming stranded on Mont Blanc in the Alps. They were part of the same expedition as two other mountaineers who were found frozen to death on a ridge, on the French-Italian border, on Saturday night. The group is said to have got caught up in a storm. "People may not have prepared properly and that was combined with very bad weather," said Michel Bordet, a mountain guide. "There were about 20 people in all who left on Friday morning," he added. The tragedy comes just days after nine other climbers were killed in an avalanche. They were swept to their deaths by a wall of snow on Thursday, as they attempted to reach the summit of Mont Blanc.
