At least 24 people, including several children, are believed to have died after one of the most powerful tornadoes ever recorded in the US flattened the Oklahoma City suburb of Moore.
President Barack Obama has declared a major disaster in Oklahoma.
Speaking to CBS affiliate KWTV, a woman described how she and her children survived the storm by hiding in the bath and pulling a mattress on top of them. They emerged unscathed, but their home was left in ruins.
"It's gone. Our car is where out house was - everything's gone," the woman sobbed.
