Some Venezuelans have taken to looting supermarkets in Caracas during the fourth day of blackouts, which have paralysed the country.

Pictures reveal that some supermarkets in the capital have been left ransacked by desperate residents as they struggle to find food.

Security forces detained a number of people who were caught looting on Sunday, with some pictures showing looters being piled onto waiting trucks.

Armed men were seen forcefully escorting young men and women to the trucks.
