Hungary announced on Thursday it would close three railway crossings with Croatia for 30 days starting from Sunday.
The locations had been used by thousands of refugees last year.
The decree from Interior Minister Sandor Pinter stated the decision would ensure "the protection of public safety," without mentioning migrants or going into other details.
Last year many refugees arrived Hungary using the crossings of Murakeresztur-Kotoriba, Gyekenyes-Koprivnica and Magyarboly-Beli Manastir to ultimately reach Germany.
Hungary erected a razor wire in late 2015 to block the path of the refugees through its southern border with Croatia after it built a similar fence on its border with Serbia.
