Eight children and two adults were injured after a roller coaster derailed and fell off the tracks at an amusement park in Scotland Sunday, NBC News reported.
Photos taken by bystanders showed the cars of the Tsunami roller coaster at M&D's amusement park in North Lanarkshire, Scotland, on the ground in a heap.
Officials initally said 11 people were injured, but authorities later confirmed that only were being treated at three hospitals. Their conditions aren't known.
Tsunami is Scotland's only inverted roller coaster, according to M&D's website. It reaches speeds of up to 40 mph, the website said.
"The ride came crashing down, landing on the kids' bike area," Ben Genovese told NBC News' U.K. partner ITV News. "Some kids got out quickly, unscathed. Others looked to be hurt."
