The Mamata Banerjee government on Friday sought help from the armed forces for the first time since Tuesday when eight districts in south Bengal were hit by flood. The air force pressed into service a helicopter to rescue 39 people who were trapped inside a two-storey house at Pratappur village in the Ghatal sub-division of West Midnapore district. Among the marooned villagers were several women and children. This was the tallest structure in the village and people took shelter in it after other houses and huts in the area were either destroyed or inundated, district officials said.
