Sir — The news of the mass massacre of school children in Peshawar has left all of us in a state of deep shock. Such a tragedy is beyond our imagination. We would never expect such brutality, even from an enemy. According to the Mahabharat, Ashwathama went to eliminate his enemies, but out of a terrible mistake, killed children while they were sleeping. later, when he realised his blunder, he lost his mental sense. Terrorists have no heart or any humanitarian sense. No softness is to be expected from them. India and Pakistan should join hands together for the annihilation of terrorism.
