YEREVAN, MAY 11, ARMENPRESS. A senior adviser to President Recep Tayyip Erdogan said Turkey would send refugees to Europe if the European parliament makes a “wrong decision” as it considers proposals to allow Turks visa-free access to the continent, “Armenpress” reports, citing Bloomberg.

The threat by Burhan Kuzu, who is also a senior member of Turkey’s ruling AK party, came as doubts grow over an agreement between Turkey and the European Union to stem an unprecedented movement of migrants from the Middle East and Africa.

Turkey was offered the visa deal, as well as financial aid and the prospect of a renewed effort toward EU membership, in return for agreeing to take back refugees. Last week, Erdogan rebuffed an EU demand that Turkey narrow its definition of terrorism in return for the lifting of visa restrictions.

Leaders including German Chancellor Angela Merkel see the agreement with Turkey as a crucial step to ease Europe’s worst refugee crisis since World War II. The European parliament will debate Turkey’s progress in fulfilling requirements for visa liberalization in its plenary session on Wednesday in Strasbourg.

“If they make a wrong decision, we would send refugees,” Kuzu said on Twitter. In a phone interview with Bloomberg, he added: “If Turkey’s doors are opened, Europe would be miserable.”

About one million people, fleeing conflicts such as Syria’s civil war, have crossed from Turkey’s shores to nearby Greek islands since early 2015. Arrivals in Greece fell to 2,987 last month from 26,971 in March and 57,066 in February, according to the United Nations refugee agency.
