On the evening of 12 September, a dispute between Eritrean and Nigerian detainees at the Khoms detention centre for 'irregular migrants' had escalated into violence, reports this Amnesty International blog post. During the chaos a group of Somalis chose their moment to escape. A 29-year-old man from the Eritrean capital Asmara, who has spent six months in various detention centres across Libya, told Amnesty International that one man in military uniform hit him on the head with a metal bar and deliberately stepped on his hand with his military boots.
