At least one person was killed and several others injured after a series of tornadoes swept through Oklahoma and Arkansas on Wednesday, officials said. One person died at a mobile home park just west of Tulsa, while three others were injured, according to the state's Emergency Management Services Authority. A storm system caused at least three tornadoes to rip through the state, including a minor one in the Oklahoma City suburb of Moore, where a deadly tornado left 24 dead and injured more than 300 others in 2013. Parts of Missouri, Illinois, Kentucky and Tennessee were under a severe thunderstorm watch. More than 78,000 customers in Oklahoma and more than 3,000 in Arkansas were without power after the storm hit the region.
