The head of the Berlin Institute for Population and Development said: “The large waves of migration have yet to come. Measures such as the Turkey Agreement and the closing of the Balkan Route ensure that currently only a few people come to Europe. “The causes of the refugee crisis, however, have not changed.”

He warned there was a "tinderbox at the gates of Europe”, with huge numbers of migrants preparing to travel from a large swathe of land stretching from West Africa to West Asia.

More than 140,000 migrants are now housed in Italian shelters, a seven-fold increase on 2013, with the migrant now crisis in its third year.
