Millions of people in states from the Great Plains to the Midwest were under the threat of tornadoes Tuesday, including Iowa, where several twisters touched down near Des Moines, causing major damage. A "devastating" tornado hit the town of Greenfield, Iowa, located southwest of Des Moines, causing fatalities and injuries in the area, Sgt. Alex Dinkla of the Iowa State Patrol said at a news conference Tuesday night. The Adair County Memorial Hospital team, which serves Greenfield, sustained tornado damage, Dinkla said, but still managed to treat patients and transport some to nearby hospitals for further care.
