Kenyan election: President Uhuru Kenyatta inaugurated in Nairobi

Delighted supporters wore the colors of the ruling Jubilee Party, cheering as they waited for the ceremony to begin. Four months of political upheaval and election chaos has left the country deeply divided.

Those inside the 60,000-seat stadium celebrated by waving flags and playing music as Kenyatta was sworn in for a second term as president. The election process has dragged on since August, after the Supreme Court annulled Kenyatta's initial victory due to "irregularities and illegalities."

Chaos erupted outside when a crowd of Kenyatta supporters attempted to force its way into the stadium, crossing the police line in droves.

Mounted police drove back huge crowds during a stampede. The interior ministry had promised big screens on which people who did not make it into the stadium could watch the event. But frustrated supporters say these were not provided.

Other officers fired tear gas canisters to keep control of the crowd. In a separate part of Nairobi, tear gas was fired at opposition protestors who had organised a "memorial rally" for the dozens killed by police violence in recent months.

Pomp and circumstance dominated the proceedings, with a military band serenading heads of states from several African nations. Leaders from Kenya's neighbors such as South Sudan, Ethiopia and Uganda were in attendance.

Kenyatta, 56, vowed to be a leader for a Kenyans — a claim that opposition supporters are unlikely to recognise. "I will devote my time and energy to build bridges, to unite and bring prosperity," he said.

Uhuru Kenyatta was sworn in by the chief registrar using a bible which his father, founding President Jomo Kenyatta, had taken his oath with in 1964. The opposition has accused the ruling National Super Alliance party of corruption, boycotting the October vote that took Kenyatta into power.
