Clarksville, Tenn. ? Devastating tornadoes ripped through Tennessee and Ohio on Sunday, killing at least 10 people, trapping others in damaged buildings and leaving thousands without power, authorities said.

At least five tornadoes swept across middle and western Tennessee packing winds up to 140 mph, the National Weather Service said.

Five people were confirmed dead and at least 21 injured in Ohio, where a weather spotter saw at least four twisters hit rural northwestern Van Wert County.

Many homes were destroyed and an undetermined number of people were trapped in damaged buildings, the Van Wert County sheriff’s department said. A county hospital worker said several people were being treated.

“We’ve got a mess,” said dispatcher Trena Bartz.

The storms cut a 100-mile swath from Van Wert near the Indiana state line to Port Clinton along Lake Erie. Emergency officials in many northern Ohio counties reported widespread damage to barns, homes and businesses.

Gov. Bob Taft declared a state of emergency in Van Wert and Ottawa counties, though storms downed power lines, closed roads and poured golf ball-sized hail in many areas of the state.

Brian Farris, of Van Wert, said he saw a tornado level a house just outside the city.

The Twin Cinema in Van Wert, Ohio, is damaged after tornadoes touched down Sunday. At least five people were killed Sunday in Ohio and five in Tennessee as severe weather swept the east-central part of the country.

“It pulled everything off, set it down, then threw it in a field,” he said. “It was on the ground at least a mile.”

Firefighters had to cut through steel to reach a trapped worker in a collapsed building at an industrial park. A five-screen movie theater outside the city was destroyed, but managers evacuated the building when they learned the storm was coming.

About 21,000 American Electric Power customers were without power in central Ohio, the company said. Thousands more homes and businesses were out in northwest Ohio, FirstEnergy Corp. spokesman Mark Durbin said. He said restoration in some areas could take several days.

At least five people were killed and 25 injured in Tennessee, including two Sunday night after a second line of storms crossed central Tennessee.

All of Tennessee’s 95 counties were under tornado watches Sunday night.

Two possible tornadoes also touched down Sunday in rural areas of southern Illinois, but no damage was reported, the weather service and local officials said. The storm system also caused damage in parts of Mississippi and Alabama, where tornadoes were also sighted.
