The US Coast Guard rescued 18 people from a floating ice floe that had recently broken loose on a lake on the Canadian border.
Despite warnings from the weather services, the group was on snowmobiles when the ice broke off the shore of Lake Erie off Catawba Island, Ohio.
The lake is one of the five Great Lakes in the northeastern United States. The border with Canada runs through it.
A Coast Guard helicopter spotted the stranded people during an overflight. In the end, seven people were rescued by helicopter, the others by boat. They were all unharmed.
The authorities posted photos of the rescue operation on Twitter.
