The Bharatiya Janata Party (BJP) and the Trinamool Congress (TMC) on Tuesday engaged in a war of words soon after activists of both the parties fought pitched battles on the streets of Kolkata during a massive roadshow by saffron party president Amit Shah, who escaped unhurt but was forced to cut short the jamboree and had to be escorted to safety by the police.
