election tension when he declared himself president in May, had 25 percent of the vote. International observers have said the first round was generally well organised and transparent but Yala said people from neighbouring Guinea had crossed the border to vote. "It's an abnormal situation which cannot happen in a country," he said. Yala's supporters marched through the capital Bissau on Friday, accusing the government of cheating. Police opened fire to disperse the crowd and three people were killed.
