In brief
Prime Minister Donald Tusk linked three recent stabbings at Polish schools to the glorification of violence online, saying the incidents were driven by spontaneous acts inspired by online content. The attacks left a caretaker dead and injured several students and adults. Over 100 arrests have been made and thousands of schools searched for weapons. Law enforcement warned of growing ultraright influence and a possible threat to high‑rank officials. Polish authorities are tightening security around schools while monitoring extremist online activity.
Prime Minister Donald Tusk says that the knife attacks at three Polish schools last week were driven by the glorification of violence online, calling them spontaneous acts inspired by internet content.
The incidents left a caretaker dead, injured several students and adults, and prompted a nationwide police sweep in which 117 people were arrested for weapons or threats against schools.
Tusk noted a rise in fascination with violence, attributing part of the violence to the influence of the extreme right and online searches for Nazi content and mass‑killer idols.
Security services convened a special meeting after receiving information of a potential threat to Tusk and Defence Minister Wladyslaw Kosiniak-Kamysz, describing the danger as “deadly serious.”
To reassure pupils, thousands of police officers visited schools across the country, and authorities warned of no large organised groups behind the attacks. However, the government remains alert for further threats and is tightening security around educational institutions.
