Macedonia has closed its borders to Afghan refugees, which has lead Greece to suggest that the number of displaced people it houses would grow rapidly as more refugees are stranded between the two countries. According to Greek police, the reason that Macedonia has tightened its restrictions on refugees is because Serbia – a nation that sits along the Balkans migration route into the west – has done the same. Macedonian officials now fear that if refugees are granted passage, that they would end up being unable to leave and be stuck in Macedonia.
