Migrant crisis: EU-Turkey deal is 'working'

Last month's EU-Turkey deal on tackling the migrant flow has begun to produce results, a top EU official has said.

"We have seen a sharp reduction of the illegal migration flows," European Council President Donald Tusk said.
In Turkey, he praised Ankara as "the best example in the world on how to treat refugees", despite criticism by rights groups of the agreement.
Turkish PM Ahmed Davutoglu reiterated the EU should now implement visa-free travel for Turks as part of the deal.
Mr Davutoglu said his country had fulfilled its part of the agreement and "the issue of the visa waiver is vital for Turkey".
Earlier on Saturday, Mr Tusk - along with German Chancellor Angela Merkel - visited a migrant camp on the Turkish-Syrian border.
The goal of the March deal is to deter migrants, mainly Syrians and Iraqis, from making illegal crossings - mainly by sea - between Turkey and Greece, an EU member.
The UN refugee agency and other rights organisations have voiced concerns about the agreement under which such illegal migrants are transported to centres in Turkey.
