People take shelter under a campaign banner as it rains during a campaign for Nigeria's former military ruler and presidential candidate of All Progressives Congress (APC) Muhammadu Buhari in Lagos January 30, 2015. Buhari pledged to cheering crowds in opposition stronghold Lagos that he would tackle the country's three greatest ills -- insecurity, inequality and corruption. Africa's most populous nation votes on Feb. 14 for either Buhari of the All Progressives Congress or President Goodluck Jonathan of the ruling People's Democratic Party.
