Kenya's rival politicians signed a power-sharing agreement Thursday and shook hands after weeks of bitter negotiations on how to end the country's deadly postelection crisis, according to The Associated Press. Opposition leader Raila Odinga referred to his rival as «my countryman, President Mwai Kibaki» _ an important sign of acceptance from a man who has said Kibaki's re-election in the Dec. 27 vote was a sham. But in a reminder of the previous weeks' chaos, police fired tear gas to disperse dozens of people who were gathered outside Kibaki's office to witness the signing. Kibaki and Odinga, both in blue suits, looked stoic as they signed the deal, side-by-side, to create the prime minister's post for Odinga that the opposition has been demanding. «For the last two months, Kenyans have known nothing but sadness,» Odinga said. Kibaki added: «This process has reminded us that as a nation there are more issues that unite than that divide us.»
