No fewer than 21 people died when a bus carrying students to their annual college entrance exam plunged into a lake in southwest China on Tuesday.
Authorities and state media say the bus crashed into a guardrail and veered into Hongshan Lake in Guizhou province, leaving 15 others injured.
The incident took place around noon in Anshun city.
Security camera footage shared on social media by CCTV showed the vehicle veering across at least five lanes — cutting into oncoming traffic — to plough through barriers on the other side of the road.
Local authorities have pledged an investigation into the cause of the accident.
