Moussa fled his warring country of Mali at the age of 12, lived alone in Algeria, survived a Libyan prison and ended up sleeping in Termini in Rome. All this before he turned 18.
Leo left Kosovo because his family's older brothers were already at university, but the family were farmers and he was the smartest one, so he had to go to Italy to work and help his brothers support themselves. To pay for the trip they sold a tractor and a cow. These are just two of the thousands of incredible lives of children, or little more, forced to leave their countries because of war or economic problems. In Italy they are called unaccompanied foreign minors (unaccompanied minors).
