A bus carrying 37 Chinese tourists crashed on a highway leading to the Canadian capital of Ottawa on Monday, injuring 24 people, including four with life-threatening injuries.
The bus veered off highway 401 and crashed into a rock embankment near Prescott, Ontario, about 90 km south of Ottawa at around 3:30 p.m. local time (1930 GMT), according to local police.
An emergency group found the bus in a ditch alongside the highway and no other vehicle was involved, the source added.
At least two helicopters, an aircraft and an ambulance were dispatched to the scene, according to a source from Ornge Air Ambulance.
A spokesman of the Chinese Embassy said that the embassy is in contact with the relevant Canadian authorities to verify the situation.
