At least 55 people died on Tuesday as the worst floods in years battered DR Congo's capital Kinshasa following an all-night downpour, according to an official toll. Major roads in the centre of Kinshasa, a city of some 15 million people, were submerged for hours, and a key supply route was cut off. City police chief General Sylvano Kasongo, in a statement to AFP, gave a provisional toll of at least 55 dead, concentrated especially on hillside locations where there had been landslips.
