July 19 (UPI) -- Tornado funnels touched down in Iowa on Thursday causing "catastrophic damage," the National Weather Service said.
The first tornado arrived in the city of Bondurant shortly after 3 p.m where it damaged at least 12 houses and upended trees and power lines, the Des Moines Register reported.
Tornado funnels continued through the state where they heavily damaged two manufacturing plants --Vermeer in Pella and Lenox in Marshalltown.
Seven people at Vermeer were injured and 10 people were being treated at a Marshalltown hospital for injuries.
No deaths were reported as a result of the tornadoes.
Marshalltown experienced overturned and missing vehicles, damaged buildings, and downed trees and utility lines, Omaha's WOWT reported.
City Administrator Jessica Kinser said Marshalltown officials declared a state of emergency.
"Everyone is advised to stay away from downtown Marshalltown until further notice," Kinser said. "We also ask that people stay off cell lines unless necessary, to allow for emergency phone traffic."
Marshalltown is located about 50 miles northeast of the state's capital city, Des Moines, and has a population of 27,500 people, Alliant Energy reported 6,690 homes and businesses were without electricity.
