More than 500 people have been killed after a cyclone devastated parts of Bangladesh. Cyclone Sidr, a category four storm, also destroyed entire villages by triggering a five-metre tidal surge that forced over 3 million people to flee their homes. Authorities expect the death toll to rise as they clear up the debris.
Starting in the Bay of Bengal, the cyclone struck the south coast of Bangladesh before weakening to a tropical storm as it passed the capital, Dhaka. After the initial impact, Bangladeshis must now deal with the aftermath: power cuts, disease and damage to crops. Bangladesh is frequently hit by storms during the monsoon season, which lasts from June to November. A severe cyclone in 1970 left more than half a million people dead.
