An official says that heavy monsoon rains have ended two successive drought years in India with the Ganges River and its tributaries rising above the danger level, triggering evacuation of hundreds of thousands of people from flooded homes in north and eastern India.

Rakesh Ranjan, a National Disaster Response Force official, says drowning, electrocution or injuries from collapsed houses have killed at least 175 people, mainly in West Bengal, Assam, Uttar Pradesh and Bihar states this season. Lightning killed 57 people in Bihar state.

Ranjan said Wednesday that the situation has been worsened by discharge of water from various dams brimming with flood waters after heavy rains in Madhya Pradesh and Uttrakhand states.

Floods occur in many parts of India during the monsoon season, which runs from June through September.
