A surveillance camera on a mast is pictured outside the main railway station in Cologne, February 8, 2016, during the "Rosenmontag" (Rose Monday) parade, the highlight of the annual carnival season in Cologne. Cologne city authorities decided to go ahead with Monday's parade, despite many other traditional Rose Monday carnival parades being cancelled in the Rhineland due to severe weather warnings.
