Poland deploys more than 20,000 police officers to schools across the country after three stabbing attacks in a short period, authorities say. The operation begins as Prime Minister Donald Tusk warns of what he calls a “grim trend” and says the government is moving to strengthen security for students.

Outlets report that officials dismiss claims that the attacks are linked to an online challenge or an organised group. Several accounts add that the government is also examining the role of violent content, including material that can be found online and in video games, in shaping youth behaviour. One report references a case involving a 15-year-old among the recent incidents.

Coverage focuses on both the immediate police presence in education settings and the wider discussion of youth violence, with reporting highlighting the authorities’ emphasis on preventive measures and investigations into possible contributing factors.
