Seven lives were lost across south Bengal as heavy downpour continued on Friday because of a well-marked low pressure that led to water-logging at several places and disruption in normal life, including suspension of railway and road communications.

While four persons, including a five-year-old child, died in collapse of walls, the rest were electrocuted.
