As part of Nigeria’s first democratic handover of power, Muhammadu Buhari was sworn in as president on Friday morning, succeeding Goodluck Jonathan.
Heads of several states, including South Africa's Jacob Zuma, and Western dignitaries such as US Secretary of State John Kerry, attended the inauguration ceremony.
Jonathan, 57, offered a prayer for the success of Buhari and showed him around his new quarters along with his new vice president Yemi Osinbajo on a tour of Aso Rock before submitting his formal handover notes.
Buhari, 72, is now the president of Africa’s top oil exporter and the continent’s most populous nation.
National expectations are high on the new president-elect to fix Nigeria’s decades old corruption and crippled economy and fuel shortage high.
Buhari also has to contend with facing the Boko Haram insurgency, which has claimed at least 15,000 lives since 2009. Under Goodluck Jonathan over 200 girls were abducted by the militant group in April 2014 and his administration was criticised for not doing enough to get them back.
Buhari has said he can’t promise the safe return of the girls but his government "will do everything in its power to bring them home."
Maximum security measures have been implemented around the square in which the inauguration ceremony will take place.
