Ex-UN chief Kofi Annan warns that ethnic rivalries, violence could harm March 4 Kenya vote

The former head of the United Nations, who helped save Kenya from spiraling deeper into election violence five years ago, is warning that intimidation, ethnic rivalry and violence could undermine Kenya's March presidential vote.

Kofi Annan said Saturday that Kenya is on a positive trajectory five years after post-election violence killed more than 1,000 people and forced some 600,000 from their homes.

Annan helped broker a political deal between the top two contenders for president. That deal saw Mwai Kibaki remain president and challenger Raila Odinga become prime minister.

Annan said he fears ethnic rivalry could see violence return when the nation votes March 4. It's likely the nation will see a run-off vote for president sometime in April that could have even more potential for violence.
