The Italian government has tried to appease protesters angry at a planned high-speed railway link between France and Italy. Ministers have promised to carry out a study on the environmental impact of a tunnel being drilled under the Alps between Lyon and Turin. At the same time, however, Rome has insisted the project will go ahead.Dozens of people have been hurt in clashes over the past week. All of the mainstream parties in Italy support the high speed train project, saying it will link the country to a network stretching from Spain to Eastern Europe. Protesters claim the work could release dangerous asbestos and uranium.
