US and UK diplomats feared Pakistan's nuclear material could fall into the hands of terrorists, the latest leaked classified US diplomatic cables reveal.
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" one of its databases from a military network.
The move is part of efforts to stop another mass leak of diplomatic cables.
In one of the latest cables to be released by Wikileaks, senior UK Foreign Office official Mariot Leslie told US diplomats in September 2009 that Britain had "deep concerns about the safety and security of Pakistan's nuclear weapons".
In another cable seven months earlier, US ambassador to Islamabad Anne Patterson told Washington: "Our major concern is not having an Islamic militant steal an entire weapon but rather the chance someone working in government of Pakistan facilities could gradually smuggle enough material out to eventually make a weapon".
