At least 24 people are confirmed dead, including seven children, and many are missing after a tornado tore through Oklahoma City, US officials say.

Worst hit was Moore, south of the city, where neighbourhoods were flattened and schools destroyed by winds of up to 200mph (320km/h).

Amateur footage posted online, which cannot be independently verified by the BBC, shows a householder emerging from their cellar to find an "apocalyptic" scene.

Emily Buchanan reports.
