Zimbabwe's president, celebrating his 89th birthday, says he believes he will resoundingly defeat his opponents in elections this year and remain in power at least another five years.

President Robert Mugabe cut an 89 kilogram (40 pound) cake Saturday in a sports arena in the mining town of Bindura, about 90 kilometers (55 miles) northeast of Harare. Youth groups of his ZANU-PF party said they walked to the bash to celebrate his "walk through a life of struggle against colonialism and Western imperialism."

Mugabe said Saturday he was confident his ZANU-PF party will triumph at the polls and accused his rivals of claiming a recent increase in political violence to cover up an upcoming election defeat under the guise that the polls would not be free and fair.
