Seven people were killed, including two children, when several tornadoes swept through central Iowa, destroying homes and knocking down trees and power lines in the state’s deadliest storm in more than a decade, authorities said.

Emergency management officials in Madison County said four were injured and six people were killed Saturday when one tornado touched down in the area southwest of Des Moines near the town of Winterset around 4:30 p.m. Among those killed were two children under the age of five and four adults.

In Lucas County, about 54 miles southeast of Des Moines, officials confirmed one death and multiple reported injuries when a separate tornado struck less than an hour later.

The state Department of Natural Resources said that person who died was in an RV at a campground at Red Haw State Park in Chariton, Iowa.

Thunderstorms that spawned tornadoes moved through much of Iowa from the afternoon until Saturday night with storms also causing damage in the Des Moines suburb of Norwalk, areas just east of Des Moines and other areas of eastern Iowa. The storms were fueled by warm, moist air from the Gulf of Mexico.
