Missing Pakistani nuclear 
                        scientists may be staying in North Korea helping develop 
                        its uranium-based nuclear weapons programme, reports said 
                        on Sunday.
                      Yonhap news agency, citing a report from 
                        the state-run Korea Institute for National Unification 
                        (KINU) in Seoul, said North Korea might have achieved 
                        a higher level of technology for enriched uranium with 
                        the help of foreign scientists.
                      “Nine Pakistani nuclear scientists 
                        have been missing since they left their country six years 
                        ago and we cannot rule out the possibility that some of 
                        them are in North Korea,” KINU researcher Jeon Sung-Hun 
                        was quoted as saying.
                      North Korea’s highly enriched uranium 
                        programme was at an early stage in its development, he 
                        said. “However, we should be prepared to find that 
                        North Korea has received a level of technology and cooperation 
                        from Pakistan, Russia, Kazakhstan, Ukraine and Belarus 
                        which surpasses general expectations,” he added.
                      The nuclear standoff on the Korean peninsula 
                        flared in October 2002 when Washington accused North Korea 
                        of running a secret nuclear programme based on enriched 
                        uranium.
                      North Korea has acknowledged having a 
                        plutonium programme but denies that it is enriching uranium 
                        to make nuclear fuel. It has rejected US demands for a 
                        complete dismantling of its nuclear programmes without 
                        receiving rewards first
