Incredible footage shows the moment a fireworks factory explodes near Granada, Colombia, south-east of the capital Bogotá, shooting rockets and showers of sparks in all directions.

The cameraman was blown off his feet as he filmed the blast before running for cover.

The blast and the resulting fire destroyed five warehouses where gunpowder was being stored, authorities said.

Investigation is on going to determine why the factory blew up.
