The BJP on Monday slammed West Bengal Chief Minister Mamata Banerjee for banning the movie "The Kerala Story", which claims to depict the plight of women converted to Islam and recruited by Islamic State, and said her decision raises serious questions on civil liberties and freedom of expression.

BJP's I-T department head Amit Malviya said the decision is unfortunate as the movie gives a "real account of victims who have endured the horrors of demographic invasion and have been used as cannon fodder" for the terrorist organisation IS.
