Nigerian president wins re-election

LAGOS, Nigeria -- Nigeria's president urged opposition parties to accept his landslide re-election, trying to head off violence after his rivals complained the balloting was rigged.\nOut of more than 42 million votes, President Olusegun Obasanjo won 62 percent in the weekend ballot, compared with 32 percent for his leading rival, former junta leader Muhammadu Buhari, the election commission announced Tuesday. More than 2.5 million votes were declared invalid.\nNigeria's main opposition party said Wednesday it would mount a legal challenge to Obasanjo's re-election on the grounds that the vote was rigged. International election observers also have worried about fraud.\nBefore the election, Buhari threatened mass action if the vote was rigged. But his party's announcement of plans to take legal action suggested they were backing down from those threats.\n"We are going to go through the entire legal system to expose the scope of this fraud," Chuba Okadigbo, Buhari's running mate, told The Associated Press.
