WASHINGTON: Seven people were killed when a devastating tornado swept through northwestern Ohio, a state emergency management official told foreign news agency on Sunday. "All seven deaths were a result of the tornado," said spokeswoman for the Ohio Emergency Management Agency, adding that the fatalities were from a tornado that touched down in Wood County, southeast of Toledo, Ohio. As many as seven tornadoes touched down in northwestern Ohio late Saturday and early Sunday morning, according to data from the US National Weather Service. A five-year-old child was among the dead in the small town of Millbury, Ohio, local media reported, citing Lake Township Police Chief Mark Hummer. Heavy storm winds were already raking Millbury when the main twister touched down at around 11:00 pm Saturday, destroying some 50 homes, businesses, and the roof and walls were ripped from the local high school, local officials said. A dozen people were hospitalized following the tornado.
