Extremely severe cyclone 'Amphan' has killed at least 12 persons and ravaged Kolkata and several parts of West Bengal as it left behind a trail of destruction by uprooting trees, destroying thousands of homes and swamping low-lying areas of the state. While a man and a woman were killed when trees came crashing down on them in North 24 Parganas district, a 13-year-old girl died in a similar incident in adjoining Howrah, officials said. Three persons were killed in Hooghly and North 24 Paraganas districts due to electrocution, they said.

A woman and her seven-year-old son were killed in the Regent park area of Kolkata after a tree fell on them, the officials said. They said a person was killed in Kolkata after being hit by a flying object during the storm. Senior state officials said it was too early to estimate a toll on life or damage to property as the hardest hit areas were still not accessible. Packing heavy rain and winds with speeds of up to 190 kmph, extremely severe cyclone Amphan slammed Digha coast of West Bengal at 2.30 pm on Wednesday, triggering heavy rainfall and gustings in various parts of the state.
