At least five people have been injured after an axe-wielding man went on a rampage at a Dusseldorf train station.
Two people have been arrested and German anti-terror police believe that others are now on the run.
Reports claim that one of the attackers ran towards a nearby underground station and jumped from a bridge as they attempted to flee.
Pictures from Düsseldorf Hauptbahnhof, the city's main station, showed one of the victims lying helplessly on the floor as paramedics rushed to their aid.
Police could not confirm how serious victims' injuries are, but some were seen treated in ambulances at the scene.
