Turkey's President Recep Tayyip Erdogan has threatened to open his country's borders and allow migrants into Europe. His statement comes after the European Parliament voted to freeze talks on Turkey's accession to the bloc. 

"When 50,000 migrants were stuck at the Turkish-Bulgarian border, you asked for help. You began to ask us 'what will we do if Turkey opens its borders?' Listen to me. If you go any further, then the frontiers will be opened. Bear that in mind," he said.

The European Parliament resolution is non-binding. And it has not received much backing, as most European leaders fear Turkey will respond by refusing to collaborate on migration.  

Brussels forged a deal with Turkey to stop migrants from entering Europe on March 18th. Turkey agreed to maritime and land border controls in exchange for incentives like visa-free travel benefits and fast-tracking membership talks.

However, little progress has been made on a number of promises, and Ankara has begun accusing Brussels of not keeping its side of the bargain.
