Milan Expo 2015 – has opened in northern Italy with food as the theme.
The food-based-fair, which opened last Friday, will turn around the “Feeding the Planet, Energy for Life” theme, with 145 countries from all over the world display their attempt to create sustainable food sources.
But right away after the opening, protesters in Milan clashed with police, who responded with tear gas.
Some groups have censured the fair, calling it a symbol of big business interests, and held protests.
Meanwhile Italian Prime Minister Matteo Renzi said: “Today it is as though Italy is embracing the world.”
