World of walls: How 65 countries have erected fences on their borders – four times as many as when the Berlin Wall was toppled – as governments try to hold back the tide of migrants

Globalisation was supposed to tear down barriers, but security fears and a widespread refusal to help migrants and refugees have fuelled a new spate of wall-building across the world, with a third of the world's countries constructing them along their borders.

When the Berlin Wall was torn down a quarter-century ago, there were 16 border fences around the world.

Today, there are 65 either completed or under construction, according to Quebec University expert Elisabeth Vallet.
