Brazilian authorities say more than 100 people have been injured after a section of bleachers collapsed at a car race.
Firefighters say at least 111 people were hurt - 22 critically.
They were taken to hospitals after the accident in Brazil's southern Parana state.
At least 500 people were sitting in the section of bleachers that collapsed.
Authorities say they think the bleachers had structural faults that caused the collapse.
However, a police investigation must end before a definite cause can be determined.
