Two people died and more than 40 others were injured after a tornado ripped through a US mobile home park.
The tornado struck Gaylord, a town of about 4,200 people, roughly 230 miles northwest of Detroit in Michigan on Friday.
In a region where tornadoes are rare, the National Weather Service said there had been winds of up to 140mph.
Fire chief Chris Martin said homes had been “picked up and turned over on top of each other”, leaving “just a very large debris field”.
He added: “Crews are in there right now doing a secondary search with heavy equipment.
