Migrants climb in the back of a lorry on the A16 highway leading to the Eurotunnel on June 23, 2015 in Calais, northern France. Some of the thousands of illegal immigrants camped in Calais and desperately trying to cross the Channel to reach Britain took advantage of a protest by French sailors blocking access roads to the Channel Tunnel on June 23 to climb onto stationery vehicles, said an AFP reporter on the scene.
