Severe storms sweeping the southern US killed at least 11 people, authorities said, as tornadoes and high winds upturned cars, destroyed homes and left tens of thousands without power. The storms hit parts of the south on Friday and were expected to move east and north on Sunday, according to the National Weather Service, which issued flood and tornado warnings for several states. Among the dead were a policeman and firefighter who were hit by a vehicle in Texas after being called out to respond to traffic accidents in icy conditions, local authorities said.
