The latest leaked classified U.S diplomatic cables reveal that the United States and the United Kingdom diplomats feared Pakistan's nuclear material could fall into the hands of terrorists. The documents released by Wikileaks, warn that Pakistan is rapidly building its nuclear stockpile despite the country's growing instability. Meanwhile, the US State Department says it has temporarily severed a database of cables from military computers. The move is part of efforts to stop further leaks of confidential material.In one of the latest cables to be released by Wikileaks, senior U.K Foreign Office official Mariot Leslie told U.S diplomats in September last year that Britain had deep concerns about the safety and security of Pakistan's nuclear weapons. Another cable concerning a U.S intelligence briefing in 2008 said despite pending economic catastrophe, Pakistan is producing nuclear weapons at a faster rate than any other country in the world. The U.S has condemned the Wikileaks disclosures as an attack on the world community. U.S Secretary of State Hillary Clinton said the diplomatic service relied as did other professions such as law and medicine, on confidential communications to conduct some important business.She said the international partnerships the US had worked hard to build would withstand the challenge posed by the leak cables.
