Croatia becomes the latest country to officially shut its borders to refugees. For refugees sneaking into the country, there's a major risk: abandoned landmines leftover from the Balkan wars of independence.
Hungary is doing its best to prevent refugees and migrants from the Middle East and beyond from entering its territory. Yet thousands of people are still on the move. So many are seeking routes around Hungary. One stop is the border between Serbia and Croatia.
As the Hungarian government races to install and reinforce more than 100 miles of new barbed wire fencing along the EU's southern border, each day thousands of migrants continue to pour across the frontier into the European Union.
