The number 70,000 include civilians and army personnel who died at the hands of terrorists, foreign mercenaries or the Pakistani Army. I cannot give you the exact distribution in terms of their religion because such figures are not disclosed by the government but the dead includes mostly the Muslims,Hindus, Sikhs and Buddhists (There arnt many Christians in any of the areas near the India-Pak border).
Moreover about a 300,000 Kashmiri Hindus have been clensed out of their homeland (Kashmir) and are rendered homeless. They have to live as refugees in their own country. The price of India's war against terrorism.
