Panic gripped central Stockholm after a double-decker bus suddenly veered off its route, slammed into a pole and ploughed straight through a crowded bus shelter. Police say several people were killed and others severely injured, but are refusing to confirm details as the investigation unfolds. Witnesses described chaos as terrified commuters ran for cover inside nearby shops, crying and covered in dust. The bus was reportedly not in active service, raising urgent questions about how it ended up tearing across Valhallavagen during peak afternoon traffic.
