The worst affected area in the state was the town of Greenfield, with a population of around 2000 people. It has been largely destroyed.
Sgt Alex Dinkla, a spokesperson for the Iowa State Patrol, said: “This tornado has devastated a good portion of this town.
“Sadly, we can confirm that there have been fatalities. We’re still counting at this time.”
