Igbo people demonstrate on Feb. 29 following the death of their leader, Dim Chukwuemeka Ojukwu, in Nnewi, Nigeria. Assaults by the Boko Haram have sent many Igbo, one of the three dominant ethnic groups in Nigeria, fleeing. Based in the eastern states, most Igbo became Catholic after being colonized by the British. Many became successful traders. (Associated Press)
