'Closing borders deflects migrant problem to others'
Croatia has closed seven of its eight road border crossings with Serbia after 13,000 migrants entered the country.
Earlier this week, Hungary fenced off its border with Serbia, prompting people to enter Croatia instead of Hungary.
Hungary has now said it will also build a fence to close part of its border with Croatia.
Dr Ivan Grdesic is the Croatian Ambassador to the UK. He said Hungary's decision was simply "shifting the burden and responsibility".
