Thick clouds of smoke from burning cars were filled parts of central Milan where groups of masked protesters, threw stones against lines of police in riot gear.
The riot came hours after the commencement of the opening ceremony at the Expo site.
It was Prime Minister Matteo Renzi who raised the curtain of the six-month-long showpiece of culture and technology focused on the theme of sustainable food production.
Police detained a number of demonstrators and at one point officers who put a woman in handcuffs were surrounded by an angry crowd demanding her release.

The Expo had already been stained by a corruption investigation that saw several top officials arrested.
Moreover, large parts of the site were not ready during the opening day.
