UN says 850,000 to cross sea to Europe in 2015 and 2016

The UN refugee agency UNHCR called for more cohesive asylum policies to deal with the growing numbers.

Many are refugees from Syria, driven to make the voyage by intensified fighting there and worsening conditions for refugees in surrounding countries due to funding shortfalls in aid programs, UNHCR said.

"In 2015, UNHCR anticipates that approximately 400,000 new arrivals will seek international protection in Europe via the Mediterranean. In 2016 this number could reach 450,000 or more," it said in an appeal document.

Spokesman William Spindler said the prediction for this year was close to being fulfilled, with 366,000 having already made the voyage. The total will depend on whether migrants stop attempting the journey as the weather gets colder and the seas more perilous.

So far, the numbers do not appear to have slowed down as the colder months approach, with many appearing spurred on by Germany's announcement that it will ease the rules for Syrians seeking refuge who first reach the European Union through other countries.

A single-day record 7,000 Syrian refugees arrived in the former Yugoslav republic of Macedonia on September 7, while 30,000 are on Greek islands, most of them on Lesbos, it said.

Many arrive first in Greece, then leave the EU to travel up through the Balkans to Hungary and onward to Germany.

UNHCR chief Antonio Guterres called for an increase in the number of legal ways for refugees to come to Europe, such as an increase in number of visas and ways to reunite people with their families.

Germany told its European partners on September 7 they must take in more refugees as it handles record numbers of asylum seekers.

The European Union's executive Commission is expected to unveil a program this week that would redistribute 160,000 asylum seekers who arrive in Italy, Hungary and Greece.
