Search for US tornado survivors goes on

Emergency crews have been digging through the rubble for survivors of deadly tornadoes that ripped through several
central and southern states of the US. At least 16 people died in Arkansas, Iowa and Oklahoma - 14 of them in the suburbs of Little Rock, Arkansas. 

Forecasters have warned millions of people to prepare for more severe storms in the region on Monday. A large tornado damaged homes and utility lines in Tupelo, Mississippi. The North Mississippi Medical Center in Tupelo admitted six people with injuries, but they are not thought to be life- threatening.

Tupelo Mayor Jason Shelton told CNN the damage was widespread and "devastating". A 9pm curfew is in place. There are warnings of further tornadoes, high winds and large hailstones to strike parts of Alabama, Iowa and Louisiana.
"We've got a powerful storm system affecting the eastern two-thirds of the United States over the next few days,'' said Russell Schneider, director of the Storm Prediction Center in Norman, Oklahoma.
