ROME (AP) — Thousands of protesters and strikers calling for solidarity with Palestinians in Gaza took to the streets in Italy on Monday, with some storming Milan’s central train station and clashing violently with police.

Italy’s grassroots unions, which represent hundreds of thousands of people ranging from schoolteachers to metalworkers, called for a 24-hour general strike in both public and private sectors, including public transportation, trains, schools and ports.

The strike caused disruptions across the country, with long delays for national trains and limited public transport in major cities, including Rome.
