Authorities across Europe are bracing for another weekend of unrest. Paris has ordered an overnight curfew in parts of the city center through Nov. 2, Italy's nationwide general strike on Friday ended in clashes with police in Rome and Bologna, and shop owners in Germany's largest cities covered their windows with plywood ahead of Saturday's protests.
Paris orders overnight curfew
The Paris police prefecture announced a partial curfew from 11 p.m. to 6 a.m., in effect from Saturday, Oct. 31, through Nov. 2, in the areas around Place de la République and Châtelet-Les Halles. A separate curfew starting at 9 p.m. will apply to minors.

Interior Minister Laurent Nuñez warned of a "very high risk of urban violence" on Saturday. Between 100,000 and 150,000 people are expected to march in Paris. Officials rejected a protest route from Bastille to Nation and directed the marches onto the boulevards des Maréchaux that ring the city.
France will deploy 70,000 police officers and gendarmes nationwide for what will be the third straight Saturday of protests, after demonstrations on Oct. 17 and Oct. 24. More than 2,500 shops were looted and about 2,700 people were detained during the Oct. 17 protests.
Italy's general strike turns violent
In Italy, a general strike called by the grassroots union USB brought marches in about 60 cities. Demonstrators carried Palestinian flags alongside union banners, reflecting the support for Gaza that has run through Italian labor protests for months.
In Rome, about 300 people broke away from the main march near the Colosseum and hurled bottles at police. They built barricades out of dumpsters in the Celio neighborhood facing the ancient amphitheater and set trash bins and scooters on fire.
Police stopped the march from reaching the Ponte Sisto bridge and detained eight people. Prime Minister Giorgia Meloni said security had been guaranteed despite the violent groups.
In Bologna, protesters shut down the city's ring road, and access roads to the A14 and A13 highways were closed for a time as union members carrying red flags scuffled with riot police.
Rome and Bologna also saw clashes during the Oct. 24 protests, when police used water cannon on demonstrators trying to march on the prime minister's office in Rome. After two days of unrest in Milan, the government sent 500 soldiers to reinforce police in the city.
German shops board up windows
In Germany, luxury retailers on Berlin's Kurfürstendamm, including Gucci, Chopard and Tiffany, covered their storefronts with wooden panels ahead of the "Gen Z" protests planned for Saturday, which falls on Halloween.
In Hamburg, the jewelers Wempe and Bucherer said they would keep their stores closed on Saturday, and shops on the Jungfernstieg also boarded up. Similar measures were taken on Düsseldorf's Königsallee and in Frankfurt.
Police said they had no indications of organized looting, and the organizers have said they reject violence.
