Nigerian President Muhammadu Buhari (C) arrives for a photo opp at the 25th African Union Summit in Sandton South Africa on June 14, 2015. Sudanese President Omar al-Bashir joined a group photograph of leaders at the African Union summit in Johannesburg on Sunday despite the International Criminal Court calling for him to be arrested at the event. Wearing a blue suit, he stood in the front row for the photograph along with South African host President Jacob Zuma and Zimbabwe's President Robert Mugabe, who is the chair of the 54-member group.
