Kolkata is going through a haunting nightmare from the flyover accident and it is speculated that 23 people were killed, over 60 injured and many others trapped as a section of an under- construction flyover today collapsed on a congested road intersection. An accident that came as a major embarrassment to ruling TMC bang in the middle of elections. Unsure the death toll at 23 after the collapse of the huge girder that crushed people and vehicles which the flyover builder described as an "act of God", drawing flak. The West Bengal government ordered a high-level probe into the tragedy that triggered a blame game with the opposition accusing the Mamata Banerjee government of callousness. And in defense the Trinamool Congress said the previous lefy front government during the whose rule the construction of the flyover began was responsible for the collapse. The police said that 23 persons died in the mishap in the Burrabazar area, which houses the city's largest wholesale market, while several others were injured. The injured were rushed to the hospitals in the vicinity. Two policemen and one Jorabagan traffic sergeant Sandip Haldar were critically injured.
