"We have forced them [to receive migrants] by sending people there. And we will continue to do so," Milanovic said at a press conference in the eastern city of Beli Manastir, from where Croatian authorities sent buses with migrants to Hungary on Friday.
On Friday, the prime minister said that Croatia was no longer capable of registering and hosting all the refugees arriving in the country, and therefore had decided to transport them to its external borders by bus.
Hungary’s Foreign Minister Peter Szijjarto condemned Croatia's decision to send migrants to external borders amid the influx, particularly to its border with Hungary.
The closure of the Serbian-Hungarian border and the penalties introduced on Tuesday by the Hungarian government for illegal border crossing have forced thousands of migrants to reroute from Serbia through Croatia and Slovenia in their attempts to reach wealthier EU states.
