Multiple school stabbings occur across Poland within one week

Three people were stabbed at schools in Poland's Mazovian region in October 2026, and one woman died. The attacks happened at three different schools over four days. In one attack, a 15-year-old boy killed a school caretaker and hurt two other adults. One attacker wore a camera on his helmet, apparently to record what he was doing. Police believe the attacks may have been connected to an online challenge. Prime Minister Donald Tusk said that websites glorifying violence helped cause the attacks. After the attacks, police searched tens of thousands of schools across the country and arrested 117 people for carrying weapons or making threats. More than 50,000 extra officers were sent to patrol towns and cities.
