Amateur video posted on social media of powerful tornadoes ripping through Iowa looked like scenes right out of the movie Twister.
The dramatic images showed the roofs of homes torn to shreds as tornadoes waded through rural parts of the Hawkeye State on Thursday.
A flurry of tornadoes swept through central Iowa, flattening buildings and damaging the courthouse in Marshalltown and hitting an agricultural machinery plant in Pella as people were working.
Authorities said a hospital was evacuated and there were some injuries from the storms.
Hardest hit appeared to be Marshalltown, a city of 27,000 people about 50 miles northeast of Des Moines, where brick walls collapsed in the streets, roofs were blown off buildings and the cupola of the historic courthouse tumbled 175 feet to the ground. The city declared a state of emergency Thursday evening.
