There is growing concern over a lack of preparation for the plan to send migrants back from Greece to Turkey, a day before it goes into effect.

A BBC correspondent who has been to one of the registration sites in Turkey says there are few signs it is ready.

The UN and rights groups have expressed fears about migrant welfare and whether some may be forced back into Syria.

The EU-Turkey deal is aimed at easing the uncontrolled mass movement of people into Europe.

Under the deal, migrants arriving illegally in Greece are expected to be sent back to Turkey from 4 April if they do not apply for asylum or if their claim is rejected.

An EU official said it was hoped that several hundred would be returned on Monday.

Saturday saw protests in Greece and Turkey. At the Idomeni camp on the Greece-Macedonia border, locals blocked a road demanding the migrants' evacuation to centres inland.

In the Turkish town of Dikili residents protested against the prospect of accepting migrants expelled from Greece.

For each Syrian returned, a Syrian migrant in Turkey will be resettled in the EU, with priority given to those who have not tried to enter the EU illegally.

Germany said on Friday it would take the first migrants.

Interior ministry spokesman Tobias Plate said that most would be families with children, with the numbers in the "double-digit range".

Last year, more than one million migrants and refugees arrived in the EU by boat from Turkey to Greece.

Tens of thousands have been stranded in Greece after northern countries closed their borders.

Meanwhile, Austrian Defence Minister Hans Peter Doskozil has said his country is planning to introduce stricter border controls at the Italian frontier to stem the flow of migrants.

He told the German newspaper Die Welt that soldiers would be deployed with the police at the Brenner Pass, a key transit route from northern Italy, saying the measures were necessary because the EU's outer borders were not properly protected.

'Safe country' queried

Greek officials told Associated Press that Monday's returns could start from the island of Lesbos and involve migrants whose asylum claims were considered inadmissible, including those from Pakistan.

Migrants will be taken on buses and put on chartered vessels, under a heavy security escort of one police guard for every migrant, the officials said.

But the BBC's Mark Lowen, who has been to a proposed registration camp near the western Turkish town of Dikili, says the field earmarked for the centre remains empty.

He says local officials are suggesting those sent back here would only stay temporarily in Dikili before being sent to other areas of Turkey.

Our correspondent says there are grave doubts over the viability of the EU plan, not least due to concerns that migrants sent back could be mistreated, with several aid agencies and EU countries refusing to recognise Turkey as a so-called "safe country of origin".

A report from Amnesty International has accused Turkey of illegally forcing thousands of refugees back to Syria, something Turkey denies.

'Big mistake'

On Friday the Greek parliament passed by 169 votes to 107 a law allowing migrants arriving in the country to be returned to Turkey.

But there have been violent protests among migrants.

On the Greek island of Chios, hundreds tore down the razor wire fence that was keeping them in and fled the camp.

They walked to the port demanding to continue their journeys to northern Europe.

One migrant said: "Deportation is a big mistake because we have risked a lot to come here especially during our crossing from Turkey to Greece. We cannot go back."

The United Nations refugee agency has urged Greece and Turkey to provide more safeguards before the returns begin.

It said conditions were worsening daily for the thousands held on Greek islands.
