In Milan, crowds broke the city's central station glass and set on fire the American flag in front of the American consulate, forcing police to use pepper to suppress.
The organizers said more than 30,000 people took to the streets in Milan, while other protests paralyzed a Paris neighborhood, operating in the ports of Genoa, Livorno and Marghera, and blocked highways in Bologna and Tuscany.
In addition to showing solidarity with the Palestinians, the demonstrators also called on Italian Prime Minister Meloni Giorgia to suspend relations with Israel.
However, Meloni later condemned the protests as shameful, writing in X that violence is unrelated to solidarity and only harms the Italian citizen.
The female prime minister affirmed that Italy supports the two-state solution, but noted that recognizing Palestine until it is established would be opposite to the effect.

In recent days, a series of countries including the UK, Canada, Australia and Portugal have officially recognized the State of Palestine.
On September 22, it was France's turn to recognize the State of Palestine at the United Nations General Assembly in New York, USA.
In overwhelming numbers, the UN General Assembly this month passed a resolution supporting a two-state solution between Israel and Palestine, while the US and Israel still object to the document, along with several small island countries in the Pacific.
Italy is known as one of Israel's closest allies in the European Union (EU), based on historical responsibility, security cooperation and pro-Western foreign policy orientation.
