In a statement, Kibaki pledged to seek "a government of national unity that would not only unite Kenyans but would also help in the healing and reconciliation process," the BBC reported.
Post-election violence in Kenya has claimed at least 350 lives and is preventing food from reaching upwards of 100,000 displaced people, many of them children, a spokesman for the United Nation's World Food Program told the BBC.
Kibaki issued his unity statement after meeting Saturday with Jendayi Frazer, the top U.S. envoy for Africa. Earlier in the day, Frazer met with opposition leader Raila Odinga, who has accused Kibaki of cheating to win a second term in elections Dec. 27, The Washington Post reported.
Odinga has called for new elections and has said he and his party will not negotiate with Kibaki.
