More than 20 people in Germany have been injured after a man with an axe went on the rampage on a train, the BBC reports.
A police operation including a helicopter is under way in Heidingsfeld, a part of the city of Wurzburg in southern Germany.
Details are scant and contradictory at this stage but some local media are reporting 21 casualties.
Some of the victims’ injuries are thought to be life-threatening.
The German news agency DPA said police would not comment on reports in the German press that the suspect had been shot.
The train line between Wurzburg-Heidingsfeld and Ochsenfurt has been closed.
