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 Eurotunnel in the French port of Calais, as part of joint efforts being announced Thursday.

Calais has been a flashpoint in a European summer marked by unusually large waves of migrants. Since the start of June, at least 10 migrants have died trying to sneak through the Channel Tunnel in hopes of finding prosperity in Britain. Countless others have slipped through undetected on trucks and one recently on foot.
