Migrants wait to cross the Greek - Macedonia border near the village of Idomeni, in northern Greece, on September 4, 2015. Europe is facing an "unprecedented humanitarian and political crisis" as it struggles with the huge influx of refugees and migrants, the European Commission's vice-president Frans Timmermans said. "We must find European responses to a problem that cannot be resolved by countries individually," Timmermans said ahead of talks with Greek Prime Minister Vassiliki Thanou on a crisis that has seen more than 230,000 people land on Greek shores this year.
