ABUJA — Nigerians celebrated their newly reinforced democracy Friday, dancing and singing songs and praises at the inauguration of Muhammadu Buhari, the first candidate to beat a sitting president at the polls. As Buhari finished taking the oath of office in traditional robes and an embroidered cap, the crowd at Eagle Square in Nigeria's capital roared its approval. The former general then inspected troops in the plaza, decked out in colors of Nigeria's green and white flag, from the back of an open vehicle and waved at supporters. A 21-gun salute boomed over Eagle Square during the handover of power which is a turning point in Nigeria's democratic evolution. A phalanx of African leaders attended the inauguration along with France's Foreign Minister Laurent Fabius and US Secretary of State John Kerry. — AP
