Security has been stepped up in the Kenyan capital, Nairobi, ahead of the inauguration of President Uhuru Kenyatta for a second term in office.
Zimbabwe's new President Emmerson Mnangagwa has addressed a packed stadium, vowing to serve all citizens.
He said he felt "deeply humbled" to take the role. And he said he was "not oblivious to the many Zimbabweans from across the political and racial divide who have helped make this day."
He paid tribute to his predecessor Robert Mugabe - to muted applause - calling him "a father, mentor, comrade-in-arms and my leader".
