Indian teacher whose hand was cut off for an exam paper

By Soutik Biswas , Oct. 13: In 2010, the hand of a professor in India was cut off by extremists after he was accused of insulting Islam in an exam paper. Last month, the government banned the controversial Muslim group Popular Front of India (PFI), whose members had carried out the attack.
