Strong winds from severe thunderstorms raked parts of the Midwest on Sunday, tossing a school bus onto a building, destroying or damaging homes, and cutting off power to thousands of customers in Indiana and Illinois.

Emergency management agencies reported a tornado in Lawrence County, said John Erickson, a spokesman for the Indiana Department of Homeland Security. The National Weather Service has not confirmed the reports.

Footage from WTHR-TV in Indianapolis showed a school bus lying atop a flattened building in Fayetteville, about 70 miles south of Indianapolis, where the tornado was reported.

Lawrence County Sheriff Sam Craig said at least 19 houses had been damaged, including three that were leveled.

At least seven housed were destroyed near Loami, Ill., and 30 more sustained severe damage, Fire Department Chief Troy Snider said. Two horses on a farm were "lost" in the storm, he said.

Winds tore the roofs off buildings in northern Indiana and central Illinois, officials said. Meteorologist Chuck Schaffer of the National Weather Service said at least one person suffered minor injuries in Illinois, but he had no details.

In Indiana, a truck driver suffered minor injuries when winds approaching 60 mph flipped the semitrailer on its side on Interstate 65 in Tippecanoe County.

Duke Energy reported more than 2,000 customers in Indiana without power as of Sunday evening, while downed power lines left hundreds of central Illinois residents in the dark.

The weather service posted high wind warnings for portions of Indiana through Monday morning.
