NIGERIA-VOTE-CAMPAIGN-UNREST

Supporters ride in a campaign bus of leading opposition All Progressive Congress (APC) presidential candidate Mohammadu Buhari and his running mate Yemi Osinbajo as they drive past a campaign poster of Nigerian President and candidate to his re-election for the ruling People's Democratic Party (PDP) Goodluck Jonathan, in Lagos on January 24, 2015. Unknown gunmen stormed and bombed the site of a planned opposition rally outside southern Nigeria's oil city of Port Harcourt early on January 24, though police said no lives were lost. Former UN secretary-general Kofi Annan, who was in Abuja recently urged all presidential candidates and parties to rise above the personal and debate the issues that matter. Nigerian voters elect a new president and parliament on February 14, then two weeks later return to cast their ballots in gubernatorial and state assembly polls.
