Sir: Extremism is spreading like a cancer that is affecting the whole nation. The horrific attacks on churches in Lahore reignited the battle on extremism, which converted the city into a battlefield. Consequently, the violent reaction of the victims further started a new dangerous phase of sectarian conflict. Extremism is the greatest threat to the country’s long-term stability. In order to ensure peace and stability in the country, a successful operation is required to exterminate miscreants. SHIREEN HASHIMTurbat
