Congress leader Rahul Gandhi on Wednesday offered condolences to the families of those killed due to torrential rains and flooding in Kolkata and urged both the state and central governments to act swiftly to restore normalcy.

Kolkata struggled to return to normalcy on Wednesday as several areas, particularly Salt Lake and pockets of the north and central parts of the city, remained waterlogged, a day after torrential rain left at least 10 people dead, nine of them due to electrocution.
