Kenyans to vote in tense head-to-head presidential race

NAIROBI (Reuters) - Kenyans vote on Monday in a presidential election that will test whether the east African nation can restore its reputation as one of Africa's more stable democracies after a lethal ethnic rampage erupted following the 2007 poll.

Outgoing President Mwai Kibaki, the candidates and civil society groups have all appealed for a peaceful poll after the disputed vote five years ago unleashed a wave of killing by rival tribes that lasted weeks and left more than 1,200 dead.
