Separate knife attacks in Italy and the Netherlands within 24 hours left an American tourist and a Dutch primary-school teacher seriously injured, underscoring mounting concerns about public safety on European trains and at community events. In Lombardy, the tourist was assaulted on 16 July aboard a Melegnano-to-Milan regional train. According to rail security officials, three men believed to be of North-African origin stabbed the passenger in the neck and shoulder before stealing his gold necklace and fleeing at San Giuliano Milanese station. The victim was taken to Vizzolo Predabissi hospital with non-life-threatening injuries, while the Polizia Ferroviaria is analysing surveillance footage to identify the attackers. FS Security says the incident is part of a pattern that has seen roughly one assault a day on Italian trains since the start of the year. Hours later in Alblasserdam, the Netherlands, a 53-year-old teacher from nearby Dordrecht was airlifted to hospital after being stabbed during an eighth-grade end-of-year musical at the De Haven cultural centre. Police believe the teacher was trying to break up a dispute between three men when one of them drew a knife. Officers have arrested suspects aged 44, 39 and 35, one of whom sustained injuries in the altercation. Mayor Jan Willem Boerma called the attack "terrible for all the children, parents and staff" and said victim-support services had been made available. Both investigations remain open, but the back-to-back incidents have intensified debate in Italy and the Netherlands over policing, knife crime and the safety of public spaces.
