Four rollercoasters at three British theme parks will remain closed today until new safety measures have been introduced.
It's after four people were seriously injured on The Smiler ride at Alton Towers, which is also still shut.
A teenager hurt in the Alton Towers rollercoaster crash is in a "critical" condition in hospital, her lawyer has said.
Victoria Balch was among four people seriously injured when two carriages collided on the Smiler ride on Tuesday afternoon.
Her lawyer, Paul Paxton, said she was in a "critical" condition, suggesting she was more seriously hurt than previously reported.
