A roller coaster carrying 24 people has become stuck near the top of the ride and firefighters are trying to rescue them at a US amusement park.
Prince George's County fire officials were called to The Joker's Jinx roller coaster at Six Flags America in Maryland. No injuries have been reported.
Assistant fire chief Paul Gomez says the riders are sitting upright, and it will probably take a few hours to get them down.
A Six Flags America spokesman said it is not yet clear what caused the ride to stop, but that it has a computerised safety system that "performed as it is designed to".
Six Flags' website says the ride goes 60mph per hour and turns upside down four times.
