Chinese police release a video. The video is from a bus. It is full. There are around eighty people on it. It goes through a city centre. A man puts oil on the floor. He sets it on fire.
He injures thirty-two passengers. Sixteen of them have serious injuries. They are at hospital.
Police still don’t know the man’s name. The man is in hospital, too.
Difficult words: release (let people see), passenger (somebody who travels on a vehicle),serious (bad), injury (to be hurt).
