Since 2014, 2,000 unaccompanied children have crossed the borders to Europe, according to European authorities. Who are these young people in search of another life? Where are they ? What do they suffer from when they reach the «promised land»? So many questions to which the German radio sation Deutsche Welle (DW) tried to find an answer. Journalists went to meet these children in Spain, Italy and Greece and made a documentary entitled «Lost children :30,000 missing minors». A 9-year-old Moroccan boy is among vanishing refugee children. At 9 years old, Ali left behind his family to join Europe, Melilla in this case. Accompanied by his elder brother, the boy tells his story, this dangerous journey that he accomplished on the roof of a truck. Published on teh 14th of October, on the official page of DW on Facebook, the video shows how Ali made his way to Europe.
