Britain and France announced new measures on Thursday to prevent undocumented migrants entering the Channel Tunnel, while stepping up joint police operations against the people-smugglers who profit from their desperation to reach Britain, according to Reuters.

Both countries will contribute police resources to a shared 'command and control' centre in the northern French port city of Calais, Britain's Home Office said in a statement

The new joint command will 'find and disrupt organised criminals who attempt to smuggle migrants into northern France and across the Channel', it said
