At least 24 people have been killed in flash floods in Mali's capital Bamako. Dozens of homes have been washed away and witnesses reported minibus taxis full of passengers swept off by the floods. Parts of Bamako, built on the banks of the river Niger, flood every year during the country's rainy season. But citizens in Bamako tell us this year's rainfall was unprecedented. Coumba Bah Traore, a social activist in Bamako, speaks about the impact of the floods on the city.
