From Lampedusa to Berlin: Dickson Mobosi's story

For Dickson Mobosi, 34, the reality of Germany is mostly the cold earth beneath his sleeping bag, inside a tent overlooked by solidly built townhouses in Berlin.

The Nigerian is one of dozens of black African refugees living in a park on Oranienplatz, a square in the heart of the Kreuzberg district.

He and others had been living and working in Libya for years when they suddenly found themselves targets during the country's civil war in 2011 and were forced to flee to Italy.
