Turkish President Recep Tayyip Erdogan will visit Brussels on Monday for talks with European Union officials amid a standoff between Ankara and Brussels over sharing of responsibility for refugees and migrants.

The blaze at the refugee center came amid a tense standoff between Turkey and the European Union over who is responsible for the millions of migrants and refugees on Turkish territory and the thousands who have massed recently at the Greek border.

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.
