Italy security operations lead to hundreds of detentions in cities
National demonstrations against the rising cost of living, military rearmament, and geopolitical conflicts triggered a wave of security operations resulting in thousands of police identifications and hundreds of preventative detentions across major Italian cities, RaiNews reported.
Thousands Identified And Hundreds Detained In Milan And Rome
Cities across Italy operated under heavy security as authorities deployed police forces and military assets to monitor scheduled and surprise rallies.
Milan recorded the highest concentration of security checks. La Repubblica noted that out of the national totals, Milan alone accounted for 2,885 identifications, 167 preventative detentions—comprising 56 minors and 43 foreign nationals—3 arrests, and 41 denunciations. Military vehicles were stationed outside Palazzo Reale, while officers maintained a constant presence around transit hubs and subway stations.
Rome experienced severe disruptions when a faction of demonstrators deviated from the primary anti-war march and entered the Colosseum archaeological zone near the Arch of Constantine. Confrontations between participants and law enforcement near Largo di Santa Susanna prompted police to deploy tear gas and water cannons. Local authorities confirmed that 96 individuals were brought into police headquarters, resulting in 28 preventative detentions and 11 denunciations.

Clashes Erupt In Turin And Bologna While Florence Faces Transport Blockades
High tension characterized the demonstrations in Turin, where protesters launched stones, bottles, and firecrackers at police lines. Law enforcement responded with water cannons and tear gas to block access to the city center. Following ongoing street conflicts, the Turin march dispersed into smaller groups near Piazza Crispi and Corso Giulio Cesare.
In Bologna, street blockades formed using bike-sharing bicycles and waste containers along Via Marconi led to injuries requiring an ambulance. Meanwhile, demonstrators in Florence moved from Ponte Santa Trinita to block the entrance of the Santa Maria Novella railway station, facing riot police deployed to secure transit infrastructure.
Investigators Target Social Media Group Organizer Following Milan Raids
Police executed over 150 emergency searches in Milan, Monza, and twenty other Lombardy municipalities following intelligence gathered from a suspicious messaging chat discovered on a phone during the previous weekend’s disturbances. Investigators identified Youssef Siher, a 30-year-old second-generation Italian researcher and freelance journalist, as the alleged organizer behind the Instagram page known as the Movimento 17 ottobre, MilanoToday reported. Prosecutors placed Siher under investigation for public incitement to commit crimes, apology of offenses, and the newly established offense of organized violence at public demonstrations under Article 420-bis of the criminal code.
Matteo Piantedosi stated that the identification highlights the capability of investigative forces and signals an immediate state response against individuals attempting to organize aggression behind anonymity. Guido Crosetto commented that the suspect possessed educational and professional opportunities exceeding those of most peers, having interacted with prominent Italian intellectual circles.

Political Rebuffs Over Military Deployments And Security Measures
Giorgia Meloni defended the government’s security posture in response to left-wing criticism regarding the presence of military personnel in urban centers. Meloni asserted that the military protects ordinary citizens and that the primary cause for concern remains violent actors operating within public demonstrations.
Controversy also extended to international commentary. The Russian Embassy published a statement on Telegram questioning official narratives, asking why authorities consistently attribute domestic unrest to Russian hackers or citizens holding Russian passports.
