Italian Prime Minister Mateo Renzi has tried to muster support in Bologna for the country’s upcoming referendum on constitutional reform.
The rally took place despite an explosion in front of a police barracks on the outskirts of the city.
It remains unclear whether the blast was linked to the issue.
In Rome thousands of anti-government protesters took to the streets to march against Renzi’s proposed reforms.
Demonstrators argue that the proposals are anti-democratic and will curtail peoples’ rights.
