Migrant crisis: 'Welcome cooling' at borders across Europe
The United Nations is continuing to record as many as 5,000 migrants a day making the sea crossing from Turkey to Greece.
At the same time, controls at Greece's northern border with Macedonia are being tightened.
People who are not from Syria, Iraq or Afghanistan are now being prevented from travelling further north.
It means an increasing number of people are attempting to make the journey illegally, as Damian Grammaticas reports.
