Mamadou Saliou "Billy" Diallo set out from Senegal in 1999 on a long and often dangerous journey to seek his fortune in Europe and provide his family with a better life. He has just returned to Dakar to visit his wife and children for the first time in more than four years.
"I was desperate to see my wife Idiatou again - she had been through so much," Billy says.
"It has been lovely to eat home-cooked food after all this time, but soon I'll be going away again. I hope to be able to bring her to Italy with me before too long."
