Baku, October 17, AZERTAC
Migrants have begun arriving in Slovenia by bus from Croatia, after Hungary shut its border with Croatia to try to stem the numbers arriving en route to Western Europe, according to BBC.
Hungary closed its Croatia frontier on Friday and now says it will reintroduce controls on its Slovenia border.
Many of the migrants aim to continue north to Austria and Germany.
Nearly 600,000 migrants have reached the EU by sea so far this year, many travelling from Turkey to Greece.
However more than 3,000 have perished trying to cross the Mediterranean. Many migrants are Syrians fleeing the civil conflict there.
Hungary said it shut the border with Croatia after European Union leaders failed to agree its plan to send a force to prevent migrants reaching Greece.
Hungary's closure of its border with Croatia comes just a month after it shut its frontier with Serbia, which was another transit route to Western Europe.
Foreign Minister Peter Szijjarto said border controls with Slovenia would be temporarily reinstated to safeguard Hungary from a "mass wave of unidentified, uncontrolled migrants."
Hungary and Slovenia are both part of the passport-free Schengen zone, but Croatia is not.
Until Friday night, 5,000 to 8,000 people were being allowed across Hungary every day, without registration, bound for Austria.
There are fears in Slovenia, a nation of some two million people, that the latest border closure will channel many more migrants through the country.
