At least 50 people have been killed in a prison riot in south-western Venezuela, hospital staff say.

The riot was triggered when local media broadcast news that soldiers had been sent to Uribana prison in Barquisimeto to search for weapons, prisons minister Iris Varela said.

BBC correspondent Sarah Grainger reports from Caracas.
