Floods in northern and central Vietnam have killed at least 49 people in the past week

Much of Hanoi - hit by the worst flooding in two decades - is submerged under 1m (3ft) of water, and more rain is expected in the next few days. Crops have been destroyed in affected areas and the price of food has soared. Several people died during heavy rain last month. In September, floods caused killed at least 25 in Vietnam's north. The latest round of flooding to hit the country has left residents wading through streets that have been turned into rivers, with water up to their chests. Some 55,000 homes, as well as power stations, schools and offices remain submerged. Floods also contaminated city water supplies.
