Italian police fire tear gas as protesters clash near Winter Olympics hockey venue

Italian police fired tear gas and a water cannon at dozens of protesters who threw firecrackers and tried to access a highway near a Winter Olympics venue on Saturday. The brief confrontation came at the end of a peaceful march by thousands against the environmental impact of the Games and the presence of U.S. agents in Italy. Police held off the violent demonstrators, who appeared to be trying to reach the Santagiulia Olympic ice hockey rink, after the skirmish.
