Strong winds from severe thunderstorms have been raking parts of the Midwest today.

The storm winds have tossed a school bus onto a building, destroyed or damaged homes, and cutoff power to thousands of customers in Indiana and Illinois.

A spokesman for the Indiana Department of Homeland Security says emergency management officials have reported a tornado in Lawrence County. But the National Weather Service hasn't 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.

The Lawrence County sheriff says at least 19 houses were damaged, including three that were leveled.

Officials say winds tore the roofs off buildings in northern Indiana and central Illinois.

There were reports of 18 tornadoes across the midwest, including eight in Illinois, four in Indiana, two in Missouri and four in Ohio.
