A truck carrying relief goods drives past a boat as it makes its way through the flooded streets of the Bangladesh capital of Dhaka September 2. The country's longest ever floods, which have lasted nearly two months, have killed over 500 people and left millions in misery. Bangladesh's politicians have entered a war of words over the prolonged flooding, with the opposition warning of famine and the government insisting it will not allow the disaster to be used for political gain.
