Nigeria's Muhammadu Buhari, who was elected president in March, will be officially inaugurated Friday morning. The 72-year-old will be sworn in during a ceremony at 9 a.m. local time, or 4 a.m. EDT, in the capital of Abuja, Agence France-Presse reported.

You can watch the event live on Buhari's office's Periscope account, @GMBOffice. Sharegist.com will broadcast the event on its website here, and Channels Television will feature it on their YouTube channel here.

Outgoing president Goodluck Jonathan is expected to attend, as well as leaders from several countries. The dignitaries scheduled to be at the inauguration include U.S. Secretary of State John Kerry, South African President Jacob Zuma, Zimbabwe's President Robert Mugabe, China's Agriculture Minister Han Changfu and French Foreign Minister Laurent Fabius.

Buhari, a retired general in the Nigerian Army, emerged victorious from the country's controversial elections earlier this year. He ran with the All Progressives Congress Party and received 15.4 million votes to overcome Jonathan's 13.3 million, Al Jazeera reported. Buhari's victory was the first time an opposition candidate unseated a government through democratic means.

Buhari and his vice president, Yemi Osinbajo, joined Jonathan on a tour of the presidential villa on Thursday. They had an inauguration dinner that night.

In preparation for Friday's ceremony, security has increased and roads have closed around Eagle Square. Organizers have put up international flags and white flowers everywhere.

Earlier this month, All Progressives Congress Transition Committee Chairman Chief Timipre Sylva told reporters the swearing-in would be low-key, Vanguard reported.

"We are not going to be flamboyant," Sylva said. "We think that this country cannot afford a flamboyant ceremony this time because the economy is not in good shape right now. So we are actually planning to give Nigerians a sanitized and compact event which will be a source of pride to Nigerians."
