Police in the northern Italian city of Milan fired tear gas at anti-globalization demonstrators on Friday, overshadowing the first day of the Milan Expo — a six-month long global fair with more than 140 participating countries which, this year, will focus on food and combating global hunger, the BBC reported.
The demonstrators, many wearing masks for protection from the fumes, took to the streets to vent their anger at some of the world's biggest companies, such as McDonald's and Coca-Cola, as well as the public money used for staging the event, which they claim was tainted with corruption.
