Ex-student knife attack at Polish school kills one, injures two; second incident this week

A former student attacked a school in Wyszków, Poland, killing one and injuring two, following a similar knife attack in Ostrołęka on Wednesday that injured ten. The pattern of two school attacks within days suggests a potential copycat or contagion effect, though motives remain unconfirmed. This raises concerns about school security and public safety in Poland.
