At least 91 people, including 20 children, are feared to have been killed by a huge tornado which tore through Oklahoma City suburbs, officials in the US state say.
Worst hit was Moore, south of the city, where neighbourhoods were flattened and schools destroyed by winds of up to 200mph (320km/h).
About 120 people are being treated in hospitals.
President Barack Obama has declared a major disaster in Oklahoma.
He also ordered federal authorities to join in the search efforts which have continued throughout the night.
