Major tornados hit Iowa, leaving towns devastated and people injured or dead. 

Greenfield was struck by the deadliest tornado of the storm, leaving homes and businesses destroyed, and while police confirmed fatalities at a news briefing, they were unable to say how many. 

The town’s hospital was among the buildings damaged, forcing the injured to find refuge elsewhere. 

US Correspondent Kathrine Firkin told Mike Hosking that there have been brutal storms right across the Midwest, but Iowa has borne the brunt of it. 

She said that the exact death tolls are unknown as authorities are still combing through debris trying to work out who is unaccounted for.
