The Latest: Weather Service: Indiana tornado count unclear

The state's Department of Homeland Security reported early Thursday that 12 tornadoes hit the state, but later the agency revised that number to eight.

Donald Trump's running mate arrived in Kokomo by helicopter to view the damage Thursday morning, a day after heavy storms spawned tornadoes across north and central Indiana.

Kokomo Mayor Greg Goodnight said Thursday morning that he's grateful that no one was killed or seriously injured by the storm that struck Wednesday afternoon, damaging numerous houses, apartments and businesses.

Police have restricted access to storm-damage neighborhoods, saying residents must show identification to officers before entering.

Agency spokesman John Erickson says officials are still assessing the storm damage Thursday, but that the tally as of Wednesday night showed 12 tornadoes touched down in Adams, Allen, Blackford, Cass, Grant, Howard, Marion and Montgomery counties in northern and central Indiana.

Several of those tornadoes struck Howard County, where the south side of the city of Kokomo suffered extensive damage.

GOP vice presidential candidate and Indiana Gov. Mike Pence plans to leave the campaign trail Thursday to assess storm damage.

The Republican vice presidential candidate returned to Indiana from the campaign trail Wednesday evening after the National Weather Service said several tornadoes struck the state.

Pence says he'll remain in the state as long as necessary to ensure people affected by the storms have the support they need.
