Pakistan's foreign office spokesman Nafees Zakaria on Thursday during their weekly briefing\u00a0claimed that India has built a 'secret nuclear city' where a stockpile of nuclear weapons has been accumulated which is threatening the strategic balance of power in the region, according to a report in Dawn. The report states that India has been conducting tests on its inter-continental missiles. Nafees Zakaria said, "Pakistan remains committed to the principles of peaceful existence with all of its neighbours, including India." The report in Dawn also mentioned Zakaria saying that\u00a0India has been exposed by the failures of its efforts to isolate Pakistan and added that the Indian Government should reciprocate the steps of peace taken by Pakistan. You may also want to watch- The report also states that India has sufficient material and technical capacity to produce between 356 and 492 nuclear bombs, according to a study published by the Institute of Strategic Studies Islamabad. DG Disarmament at the Foreign Office, Kamran Akhtar said, "There is a fear that the Indian reactors not mandated by the safeguards might be used clandestinely for plutonium production and the existing stockpiles might be diverted to a military programme at a subsequent stage." Spokesperson of India's\u00a0Ministry of External Affairs, Vikas Swarup calls Pakistan's claim baseless, and says "Pakistan's claims of India's secret nuclear city baseless; This aims to deflect attention from real issue of terrorism."
