Uhuru Kenyatta has been sworn in as Kenya's president, the fourth since the nation gained independence, exactly 50 years ago. Kenyatta took the oath, using the same Bible as his father, Jomo Kenyatta, Kenya's first president. The US had warned of what it called consequences if Uhuru Kenyatta was voted into office - as it weighed how to deal with a leader indicted by the International Criminal Court (ICC). But US and European ambassadors did join around a dozen African leaders and government officials from around the world for the inauguration in Nairobi - a sign, perhaps, of Kenya's strategic and economic importance. For his part, Uhuru Kenyatta gave commitments on everything from the economy and employment to education and the environment.
