Migrants flooding into Croatia are being moved to the Hungary border, with PM Zoran Milanovic saying his country cannot become a "migrant hotspot".

Up to 20 buses carried migrants to the border on Friday, although Hungary says it is building a new fence there.

Croatia earlier closed seven of eight road crossings to Serbia after 14,000 migrants entered over the past two days seeking passage to northern Europe.

Slovenia, another neighbour of Croatia, accused it of breaking EU rules.

The huge numbers heading north through the Balkans have triggered an EU crisis. Many are fleeing conflicts in Syria, Iraq and Afghanistan.

Mr Milanovic said: "Hungary has closed off its border with barbed wire, that's not a solution, but these people remaining in Croatia is not a solution either."

Asked whether Croatia could send migrants to Slovenia, he said that "Hungary is three times closer".

The first buses carrying migrants arrived at the Hungarian border crossing of Beremend on Friday afternoon.
