At least 80 people have been killed and thousands evacuated after incessant rainfall lashed southern India over the past week, local media reported Monday. Tamil Nadu state was the worst-hit with at least 70 people dead and most parts of the state flooded. The India Meteorological Department (IMD) has forecast torrential rains for next three days in neighboring Andhra Pradesh state and union territory of Puducherry.

Normalcy will return soon and the government machinery is working day and night to ensure that,” Jayalalithaa said, according to the Press Trust of India news agency.
