The tram was making the trip from the leading seaside resort Ostend to De Panne when it derailed in a bend while entering the town of Nieuwpoort. The nose of the tram crashed into a pole.
The tram driver was not hurt. None of the injured is in any life-threatening condition. The cause of the accident is unclear. Excessive speed or a problem with the rails are the most likely causes.
Tram services will probably be suspended between Westende (Middelkerke) and Nieuwpoort until Saturday afternoon. Passengers will have to take a bus.
Some 100 people were on board the tram when it crashed.
