Leaks expose UK and US fears over Pakistan nuclear arms
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" a database of cables from military computers.
The move is part of efforts to stop further leaks of confidential material.
