Slovenia will ask the European Union to send police back-up to help it cope with the thousands of migrants and refugees coming into the country.
Around 19,500 have entered Slovenia since Friday after Hungary sealed its southern border with Croatia.
Speaking after a meeting with European Council President Donald Tusk and EU chief executive Jean-Claude Juncker, President Borut Pahor said:
We need fast assistance of the European Union. Slovenia will formally ask for additional police forces to guard the border between Slovenia and Croatia and for financial help.
The country has deployed 140 soldiers to the border to assist police and hasn't ruled out building a fence as part of its efforts to control the influx of migrants.
Refugees travelling through the Balkans risk freezing to death as winter begins, the president of the European Commission has warned.
