The northern French port of Calais is facing an international refugee crisis. Thousands of illegal migrants have descended on the town with the intention of making it across the English Channel to the UK, any way they can. Many are fleeing deadly wars at home and are prepared to take extreme risks. Some sneak into the back of UK bound trucks while others hide themselves in the undercarriage. Calais says it can no longer cope with the squatter camps and rising crime which accompany the gangs of desperate young men determined to make it across one of Europe's most heavily guarded borders. Darius Bazargan has been to Calais to meet the migrants, and the locals, caught up in a growing humanitarian crisis.
