Bus overturns in southwest Ohio

A Greyhound bus drove off an interstate highway in southwest Ohio early Saturday Sept. 14, 2013, struck a tree and a fence and flipped on its side before sliding to a stop in a cornfield, injuring at least 35 people.

None of the injuries was considered life-threatening, though several people were trapped and had to be extricated by firefighters and paramedics, the State Highway Patrol said in a statement. (Associated Press)
