According to a report in the "Express Tribune" newspaper the Sindh government had sent a letter to the Karachi Corps Commander keeping in mind the deteriorating law and order situation and looming terrorist threats during Ashura which is the 10th day of Muharram.
Quoting sources in the home department the report said the Sindh Chief Secretary had written a letter to the Karachi Corps Commander, asking to deploy armed forces in Karachi, Hyderabad, Sukkur, Mirpurkhas and Larkana divisions.
The army would not patrol roads but remain on alert in the district headquarters on both the days.
However the Inter-Services Public Relations (ISPR) denied receiving any such letter from the Sindh government.
Earlier, Sindh Minister for Prisons Manzoor Wasan had approved the federal government's decision to deweaponise the country and supported the idea of conducting operations in Karachi.
"Karachi has become a nursery for the criminals and it is high time to start an operation without any delay," he said.
