Tornadoes rolled in from the prairie and slammed Oklahoma City and its suburbs, trapping people in their vehicles as a storm swept down an interstate highway while commuters tried to beat it home.
Nine people were killed, including a mother and baby killed near Union City. Another person died at El Reno, the first city struck by the storm, said Amy Elliott, a spokeswoman for the state medical examiner. Circumstances involving the other two deaths weren't immediately known, Elliott said.
About 50 people were hurt, five critically, hospital officials said.
