Europe's worst migration crisis since World War II risks triggering "tectonic changes", a top EU official warned Tuesday, as figures showed more than 700,000 newcomers have reached the continent's Mediterranean shores this year.
"The situation will deteriorate even further," European Council president Donald Tusk said, warning of a "new wave of refugees (arriving) from Aleppo and other Syrian regions under Russian bombardment".
"I have no doubt that this challenge has the potential to change the European Union we have built," he told the European Parliament in Strasbourg.
