Police killed two rioters in poll violence on Sunday as Congo voted in a presidential run-off intended to end decades of war and pillage that have left the country devastated despite its mineral riches. The governor of the northerly Equateur province, Yves Mobando, told Reuters: "Two people were killed when the police opened fire to disperse the crowds." He said the police intervened in the town of Bumba, 800 km (500 miles), from Kinshasa when supporters of presidential candidate Jean-Pierre Bemba destroyed a polling station after alleging a ballot box had been stuffed with votes for his opponent, the incumbent president, Joseph Kabila. He said the official electoral commission had dismissed the allegation. International election monitors, who did not want to be identified, said turnout seemed lower around the country than at the same time in the first round on July 30.
