Kenya is inaugurating a new president — Uhuru Kenyatta.

Leaders from across Africa have flown into Nairobi to watch Tuesday's swearing-in, which is taking place at a sports stadium filled with tens of thousands of rowdy Kenyatta supporters.

Kenyatta, 51, is the son of Kenya's first president, Jomo Kenyatta. His March 4 election victory, with 50.07 percent of the vote, was upheld by the country's Supreme Court after an election challenge from outgoing Prime Minister Raila Odinga.

Kenyatta — Kenya's fourth president — becomes the second sitting African president to face charges at the International Criminal Court over allegations he helped orchestrate the vicious tribe-on-tribe violence that marred Kenya's 2007 presidential election. That trial is scheduled to begin in July. Kenyatta's deputy, William Ruto, faces similar charges at the ICC.
