The men are part of a spring migration offensive from Africa to Europe, with record numbers of desperate people risking death in their quest for a better life. They use perilous routes such as Mediterranean Sea crossings on rickety boats to the Italian island of Lampedusa or treks through desert, jungle and mountain that culminate in attempts to scale fences erected to keep them out of Melilla and Spain’s other North African enclave, Ceuta.
If they succeed and get into Spain, they will move northward to more desirable countries like Germany and the UK.
