A Somali man has been sentenced to life in prison in Italy for murdering and torturing dozens of migrants in Libya.
Osman Matammud, 22, was arrested last year after being recognised by chance in Milan.
Witnesses said he had beaten people to death and let others die from a lack of food and water.
Migrants from sub-Saharan Africa often spend time in camps in Libya while waiting for relatives to pay more money to traffickers who take them on to Europe.
