CALAIS, FRANCE - SEPTEMBER 04: A 'Welcome to Calais' sign stands next to razor wire security fencing around the Port of Calais on September 4, 2016 in Calais, France. Local farmers, truckers and business owners are taking part in a protest, dubbed Operation Escargot to block off main routes in and out of Calais. They are calling for The Jungle migrant camp at the French port to be demolished. Up to 10,000 migrants are now living at the camp and are using desperate and violent measures to try and board trucks heading for the UK. (Photo by Jack Taylor/Getty Images)
