Photos From Buhari and Osinbajo's May 29th Inauguration

Nigeria's President Muhammadu Buhari took the reins of leadership for another term on Wednesday, against a tense backdrop of insecurity and economic uncertainty.

The 76-year-old fought a fierce battle against one of the country's foremost politicians and former Vice-President Atiku Abubakar to clinch victory in the February vote -- a win that is still being challenged by the opposition.

As Eagle Square, in the Nigerian capital of Abuja, was decorated ahead of Buhari's inauguration ceremony, hundreds of people took to the streets in several cities on Tuesday in protest against a spate of kidnapping and security incidents in recent months.

They carried signs that read "Stop the Killings" and "Not Just Numbers," asking the incoming administration to prioritize citizens' security.

At a meeting with governors from northern states on Monday, Buhari said he was aware of the security challenges and promised not let the nation down.

"The security of the country is on my mind 24 hours of the day. I get daily and weekly situation reports. I have listened to your brief. I will look into your recommendations. I am acutely aware of the situation," Buhari said in a statement.

The ceremony took place at the Eagle Square. See more photos below;
