At least six people died and 30 were injured Wednesday when a passenger train collided with a bus on the outskirts of Ottawa, Canadian police reported.

Five people died at the crash scene while a sixth person died at a hospital in the Canadian capital.

Ottawa Mayor Jim Watson called the accident the worst in the city's history and confirmed that one of the dead is the driver of the double-decker municipal bus.

The accident occurred at 8:50 a.m. at a level crossing some 18 kilometers (11 miles) southwest of downtown Ottawa.

Bus passengers told reporters that the driver did not stop at the crossing despite the fact that the barrier was lowered and several passengers shouted at him to stop the vehicle.

First responders said that the dead were all occupants of the bus and that none of the train's passengers was injured despite the fact that the locomotive and several cars jumped the tracks as a result of the impact.

Television images show the totally mangled forward portion of the bus, which came to rest on the tracks at the crossing.

The same TV images also show several bodies covered with blankets at the scene. EFE
