Sindh continues to remain an ethnic powder-keg : A Leaf From History: A history of ethnic violence by Shaikh Aziz

Sindh, however, has often been the most affected because incidents of violence have left deep-rooted scars on the ethnically polarised province. Ethnic disturbances in Sindh first began in 1952 when, during an Ashura procession, some rumours created tensions between Sindhi and Urdu speaking residents and an infuriated crowd burnt down a police station. The district administration prevented further aggravation by efficiently handling the situation.
