UN outlines legal concerns on EU-Turkey deal - Main contents

The EU insists any deal with Turkey on returning migrants will be legally sound.

But outstanding issues on how people kicked out of Greece and returned to Turkey may be treated if Ankara refuses to fully apply the 1951 Geneva Convention remain.

The issue has roused concerns from the UN agency for refugees (UNHCR), which, in a four-page note on the deal, says the blanket return of rejected migrants "without key protection safeguards in place, would be at variance with international and European standards".

The UNHCR document, dated 10 March, comes ahead of a summit in Brussels this week between EU leaders and Turkey's prime minister Ahmet Davutoglu i.

European Council president Donald Tusk i in Ankara on Tuesday (15 March) said the deal hinges on making it stand up to EU and international law.

"This is not an easy task, and we have to get it right," he said.

The European Commission on Tuesday made similar comments, noting that it has been working with the UNHCR on how to make it work in practice.

"The commission has made a legal analysis of what is possible in order make the agreed deal in principle operational," a commission spokesperson told reporters.

The EU plan is to arrange speedy returns to Turkey from Greece and to stop irregular migrants from using smugglers to reach Greece via Turkey. Almost 800,000 made the trip last year.

But the UNHCR paper said that each person is entitled to an individual assessement in Greece before being returned to Turkey.

Greece can only also issue the return if key legal safeguards are guaranteed in Turkey.

The UNHCR also said that any deal which invovles the transfer of asylum seekers from one state to another should be "aimed at enhancing the sharing, rather the shifting, of burdens and responsiblities".

With 45,000 people now stuck in Greece and some 14,000 living in dire conditions at the Idomeni camp near the Macedonia border the sense of "sharing" among EU states appears to be lacking.

EU states had agreed last year to relocate tens of thousands from Greece but have so far only managed just a few hundred.

On Tuesday (15 March) thousands of migrants were forced back into Greece from Macedonia, with Austria now promising to help Skojpe guard the border by offering equipment, according to German newspaper Die Welt.

"The defence ministry is currently checking whether we can help with technical gear, such as night vision goggles," Austria's defence minister Hans Peter Doskozi told the daily.

Filippo Grandi, the United Nations High Commissioner for Refugees, last week also said asylum seekers returned to Turkey should have full access to education, work, health care and, social assistance.

Turkey hosts some 2.7 million Syrian refugees. Only 10 percent are found in 23 camps, with the rest living elsewhere in the country. An additional 121,000 Iraqis and almost 98,000 Afghan refugees are also in Turkey.

The EU, for its part, is supposed to help finance projects such as education and health for refugees inside Turkey.

But so far less than €100 million out of a promised €3 billion has been earmarked for projects.

The initial rollout earlier this month is aimed at helping Syrian school children in Turkey and enrolling others in a UN-backed food voucher programme.
