UK, France boost security

Joint effort aims to prevent illegal entry from Calais into Eurotunnel

Britain and France are fortifying security around the Channel Tunnel and boosting intelligence efforts against traffickers as they try to dissuade thousands of migrants from trying to make the illegal - and sometimes deadly - undersea journey to British shores.

Better fencing, surveillance cameras, flood lighting and infrared detection technology will be installed around the entrance to the tunnel in the French port of Calais, as part of joint efforts being announced on Thursday, according to a British statement.
