Pro-Biafra supports demonstrate on May 30, 2017 in Abidjan, during commemorations of the 50th anniversary of the Nigerian civil war. Nigeria on May 30 marks 50 years since the declaration of an independent Republic of Biafra plunged the country into a civil war, amid renewed tensions and fresh calls for a separate state. The main pro-independence groups -- the Indigenous People of Biafra (IPOB), and the Movement for the Actualisation of the Sovereign State of Biafra (MASSOB) -- have called for a day of reflection. / AFP PHOTO / Sia KAMBOU (Photo credit should read SIA KAMBOU/AFP via Getty Images)
