A double-decker bus collided with a passenger train in Canada's capital Wednesday, ripping off the front of the bus and killing six people, police said. Witnesses said the bus went through a closed crossing barrier, and passengers said they screamed "Stop, stop!" at the driver just before impact.
Officials said 30 people were injured, 11 critically. The crash in Ottawa occurred at the peak of morning rush hour. The cause was not yet clear, said John Manconi with bus operator OC Transpo.(AP)
