Turkish President Recep Tayyip Erdogan plans to be in Brussels next week for a one-day working visit, amid a charged conflict between Turkey and the European Union over migrants and refugees, The Associated Press reported.

A statement from Erdogan’s office said he would travel to Brussels on Monday. The statement did not specify where he would be during his one-day visit, or the nature of the work taking him to the Belgian capital, but the European Union’s headquarters are in Brussels.

The announcement came hours after European Union foreign ministers meeting in Croatia on Friday criticized Turkey, saying it was using the migrants’ desperation “for political purposes.”

Thousands of migrants headed for Turkey’s land border with Greece after Erdogan’s government said last week that it would no longer prevent migrants and refugees from crossing over to EU territory. Greece deployed riot police and border guards to repel people trying to enter the country from the sea or by land.

Erdogan announced said last week that Turkey, which already houses more than 3.5 million Syrian refugees, would no longer be Europe’s gatekeeper and declared that its previously guarded borders with Europe are now open.
