At least 55 people died in India's southern state of Tamil Nadu as heavy rains flooded many areas and disrupted road, rail and air traffic, dpa cited news reports as saying Friday. Over the past five days, people have died as a result of electrocution and when walls and houses collapsed, mostly in the coastal district of Cuddalore, according to broadcaster NDTV. The flooding brought the state capital Chennai to a halt as trains and flights were delayed and schools and colleges closed on Friday, the report said. Incessant rains caused water-logging in several parts of the eastern coastal city and some office-workers had to wade knee-deep through water to get to work.
