A powerful tornado has torn through a suburb of Oklahoma city in the US, leaving at least 91 people dead â€“ including 20 children.
The three kilometre wide twister, with winds of up to 320 kilometres per hour, flattened large swathes of Moore â€“ destroying everything in its path.
Search and rescue operations are continuing in the worst affected areas.
The Plaza Towers Elementary School took a direct hit. Its roof was ripped off and its walls collapsed. Emergency crews have been searching for two dozen children, thought to be buried in the rubble.
â€œThe whole city looks like a debris field,â€ the mayor of Moore, Glenn Lewis told NBC. â€œIt looks like we have lost our hospital. I drove by there a while ago and itâ€™s pretty much destroyed.â€
