How did nationwide student protests turn violent in Italy?

Students launched a nationwide strike against the Valditara decree, the cost of living, petrol prices, and vocational school reforms. On a single day of simultaneous protests, thousands marched in Rome, demonstrators pelted effigies in Genoa, and clashes erupted in Turin.

During the Turin march, teachers linked arms to separate demonstrators from police lines before stones and flares were thrown, prompting regional president Alberto Cirio to say: Anyone who throws stones, bottles or any other object at a police uniform automatically ends up on the wrong side.

Police arrested three minors for aggravated resistance after the clashes. Officers identified more than 50 protesters, some with their faces covered, and said their conduct would be referred to the judicial authorities.
