SocietyPoland examines possible Russian links to wave of school attacks

Three attacks at educational institutions in less than a week have shaken Poland and prompted a major security response. Authorities say there is no evidence they were coordinated, though concerns are mounting over copycat violence, online influences and school safety. Some politicians, including opposition leader Jarosław Kaczynski, allege Russian influence operations may be encouraging such violence online, but no evidence has been presented.
