The suspect’s identity and motive remain unclear, though he was heard making incoherent statements. Authorities are considering whether to treat the attack as terrorism. Witnesses described the chaotic scene, with bystanders helping to subdue the attacker. This violent act follows a recent attack in Berlin, raising concerns about public safety.
