Footage has been recorded by the BBC showing the extreme lengths a group of armed people-smugglers were prepared to go to to get migrants in Calais across the Channel to Kent.

The masked men blocked the main route to the French port with a felled tree.

BBC South East witnessed migrants being directed to break into lorries brought to a sudden halt.

Special correspondent Colin Campbell and his producer said the people-traffickers were "ruthless and territorial", controlling the situation armed with large sticks.
