Sir: The land of Sindh is famous for tolerance and brotherhood worldwide. Before the partition of the subcontinent, there was a time that Hindus and Muslims used to celebrate their religious festivals together. For a long time religious harmony remained a part of Sindh and many great personalities of Sindh gave the message of peace, tolerance and brotherhood to the world. In the previous year in district Tharparkar, which is plagued by famine that claimed the lives of several innocent children, a large number of Sindhi Hindus participated in the Muharram procession in Tharparkar and it was a crystal clear proof of religious harmony. At the same time when Sindh was giving the message of religious harmony and brotherhood, an incident took place in Punjab where a Christian couple Shama and Shahzad were burnt alive in a brick kiln in November 2014 in Kot Radha Kishan. In the same year various incidents of religious extremism took place in Sindh, such as the temples of Hindus being burnt in different parts of Sindh, especially Larkana’s Dharamshala and the Tharparkar, Hyderabad and Tando Mohammad Khan incidents of burning Hanuman’s temples. All these were highlighted by the national and international media. After the rise of religious extremism in Sindh, several incidents of sectarian violence and killings took place, especially in Karachi. Hundreds of people, mostly belonging to the Shia sect, were killed in sectarian violence. Most of the culprits are roaming freely without any fear in Karachi and other parts of Sindh because the situation of law and order is bad all over Sindh. The existence of a secular Sindh is in danger because the banned religious extremist outfits have spread their networks at the union council level and their activists organize seminars, meetings, protests and rallies across the country. The government should take this issue very seriously and evolve a strategy to check religious extremism in Sindh and all over Pakistan. JIBRAN KHASKHELI Tando Mohammad Khan
