The past two decades have witnessed a notable escalation in sectarian violence in Pakistan. Since 1979 doctrinal disputes between Sunnis (who constitute the majority of Pakistan's population) and Twelver Shi‘is (who number between 15% and 25% of the population, and are to be distinguished from Islami‘ili, Khoja and Bohri Shi‘is) has given place to full-fledged sectarian conflict. Militant Sunni and Shi‘i organizations have carried out assassinations and bombing campaigns that have killed political rivals as well as children and the innocent at prayer in mosques. In the first seven months of 1997 alone—the year when sectarian conflict reached its apogee—one hundred people died in such attacks in Punjab. The violence escalated further when in the first ten days of August 1997 (immediately preceding the celebration of the fiftieth anniversary of the country's independence) another seventy people were killed in incidents of sectarian violence.
