Food riots erupted on Wednesday in eastern India, where more than two million people have been forced from their homes and about 250,000 houses destroyed in what officials say are the worst floods in 50 years. One person was killed in Madhepura district when angry villagers fought among themselves over limited supplies of food and medicines at overcrowded relief centres, Reuters reported. The Kosi river in Bihar, one of India's poorest states, smashed through mud embankments and changed course last week, unleashing huge walls of water that inundated hundreds of villages and towns. The floods have since killed nearly 50 people in Bihar. Torrential rains have killed more than 1,000 people in South Asia since the monsoon began in June, mainly in India's northern state of Uttar Pradesh but also in Nepal and Bangladesh.
