prisoners, she said. we are humans. we escaped frommisise and we came to you-- from i.s.i.s. and we came to you. if there was any hope that the bottleneck at the border would be solved in a few days, it was all but gone. anger and frustration and an overwhelming state of confusion pervades. access to macedonia is restricted but no clear guidelines have been given as to what the stranded here need to do. information is pressed by word of mouth and often it is wrong - spread by worth of mouth >> translation: every day there are new rules. i'm afraid when my time comes i'm afraid to get in. >> reporter: any semblance of a unified european system has

completely broken down. many of the registration papers issued by greek authorities are not valid any more. macedonian and balkans require a new stamp. so many stand in queue for hours, even though there are no guarantees that will end their plight. another source of anxiety can the turkish stamp on passports. this man, like many here, he first stopped in turkey to earn enough money to pay the small letter. >> i was there for one month >> reporter: what does that mean for you? -- smuggler. >> what does that mean for you? >> translation: >> is hard to come all this way without sleeping or food and then you hear in the news that you capital get in because you have been in turkey one month. >> reporter: police are struggling to keep order. they have been organising refugees into numbered groups of

referendum on the e.u. membership. high on the agenda was the situation in the french refugee camp known as the jungle. >> reporter: a century ago france and britain fought shoulder to shoulder in the fields around the modern city of ammion. there was heavy symbolism in president francois hollande and president cameron at the war memorial. they got down to business, an agenda dominated by their bilateral cooperation on refugees and security. an arrangement potentially threatened by the impending british referendum on e.u. membership >> translation: i don't want to scare you. i just want to say the truth. there will be consequences if the uchlt k is to leave the e.u. there will be consequences in many areas, on the single market, on financial trade, on economic development. i don't want to guf you you a catastrophic scenario but there will be consequences - give. >> reporter: there was progress

in a promise that unaccompanied refugee children will be allowed to join relatives already in the u.k. the response was to simply promise more financial support so most refugees stay on french soil. >> we will invest an additional 70 million pounds in priority infrastructure in calais to assist the work of the french police. the money will go towards efforts to move people from the camps in calais to facilities elsewhere in france and we will fund joint work to return migrants not in need of protection to their home countries. the real challenge is in the eastern mediterannean where we need to break the business model of the people smugglers and persuade people on embarking on a perilous journey. >> reporter: the camp here have been flattened.
