Dubbing the killing of eight people in West Bengal's Birbhum as reminiscent of a "Nazi concentration camp", the BJP Thursday attacked Chief Minister Mamata Banerjee, saying she showed no "mamata" (affection) and was "nirmam" (cruel). Eight people, mostly women, and children, were burnt alive at Bogtui village of Birbhum district early Tuesday in suspected retribution for the killing of a ruling TMC panchayat official. The incident has sparked national outrage, with West Bengal's main opposition party BJP demanding President's rule in the state.
