In 2015, after Hungary built a fence along its border with Serbia, over 17000 refugees crossed the border into Croatia. They are seeking an alternative route into the Schengen area, as part of the refugee crisis, with most refugees fleeing the Syrian and Iraqi civil wars. As the Croatian Prime minister Zoran Milanović stated that Croatia could not become a "refugee camp" and that it had become overwhelmed by the number of refugees entering the country, it was decided that Croatia would stop registering them and that a certain number of refugees be let into Hungary and Slovenia, attempts were made, however, by the authorities of those countries to obstruct the passage of refugees. The refugee crisis and immigration may also, for the first time in Croatia's history, become a subject of political debate during the next Croatian parliamentary election to be held in 2015.
