ISLAMABAD - Chief of Army Staff (COAS) General Ashfaq Parvez Kayani on Thursday said there was no need of an army operation in Karachi and Rangers were performing their duties well in the City.General Kayani was apparently responding to the demands from politicians to launch army operation in Karachi. Speaking to media representatives on the sidelines of the D8-Summit, the army chief expressed his satisfaction over the current security arrangements deployed in the metropolis.Lauding the role of police and Rangers for restoration of peace in the Sindh capital, Kayani said both the law enforcement agencies were performing their duties to the best of their abilities. “Contingents of police and rangers are deployed at all sensitive points in Karachi,” he added.Commenting on army’s role during Muharram, he said the armed forces were ready to render any help for maintaining peace in the country during the Muslim holy month. “Army is ready to lay its hands in maintaining peace and controlling terrorism during Muharram,” said Kayani.He, however, said it was civilian government’s prerogative to call armed forces for any help to maintain law and order in the country. “We can’t take control of the situation on our own,” he added.On Wednesday, IG Sindh Fayyaz Leghari said an army operation should not be conducted in Karachi, adding that the capacity of the already present paramilitary forces in the city should be increased.Earlier, lawmakers from the Awami National Party (ANP) demanded an immediate military operation in the troubled city, saying that the Sindh government had failed, while Karachi’s ruling party, the Muttahida Qaumi Movement (MQM), staged walkouts from both houses of the parliament to register their protest against the government’s inaction.
