>> As dawn breaks over the waterlogged plain of Evros on the border between Greece and Turkey, a line of refugees emerges through the morning haze. They've made it across the Evros River, which is fast becoming the preferred route for migrants crossing into Europe. Omar Waleed is from Aleppo.
He fled Syria six months ago after losing his father and son.>> I'm very tired. It's very bad. Here it's very good but the way it's very bad.>> In April alone, at least 2,900 people arrived in Greece through these waters. That's already half the estimated number for the whole of 2017 according to the United Nations Refugee Agency.
Police and local government officials in the region are concerned.
2015 nearly a million refugees and migrants crossed from Turkey to Greece's islands. But that route all but closed, after the EU and Ankara agreed to stop the flow in March 2016. This land border doesn't appear to fall under the agreement.
It takes around five to six minutes to paddle across the Evros River, a much favored route compared to the harrowing journey in over-crowded rafts to make it to Greece's islands. But these fast-moving waters are still treacherous. 12 people died here in the first three months of the year.
Those who do survive the crossing are taken to be registered and given a three month residents permit. Theoretically, they're free to move around Greece, unlike those on the islands
