Slovenia’s army will help police deal with thousands of migrants expected to arrive from Croatia in the coming days, Prime Minister Miro Cerar says.

His announcement came as hundreds of migrants began arriving on its borders with Croatia –– a day after Hungary closed its frontier with Croatia.

Many of the migrants aim to continue north to Austria and Germany. More than 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.

Slovenia’s Prime Minister Miro Cerar said the government had decided “to include the army in helping police”.

He was speaking after a meeting of the country’s National Security Council.

Throughout the morning, some 600 refugees at a reception centre near Croatia’s border with Serbia were bussed to two border crossings into Slovenia.
