At least one person has died and three others have been critically injured in an incident at an Australian theme park.
Australian media reported it appeared one person had become caught in a conveyor belt on the Thunder River
Rapids family ride at Dreamworld on the country's Gold Coast.
It was also claimed that one of the ride's six-seat tyre-style carriages flipped on the conveyor belt that takes ride users back to the boarding and disembarking area.
