WASHINGTON, April 14: President George W. Bush has credited his administration with unravelling a dangerous network of nuclear proliferators headed by Dr Abdul Qadeer Khan.

In his Tuesday night news conference, Mr Bush presented the busting of nuclear scientists' network as one of his administration's major victories in the war against terror.

"The A.Q. Khan bust, the network that we uncovered" was another victory in the war against terror, he said. Mr Bush described the group as a shadowy network of folks that were willing to sell state secrets to the highest bidder.

Dr Khan's network, he said, had made the world more unstable and more dangerous. "You've often heard me talk about my worry about weapons of mass destruction ending up in the hands of the wrong people. Well, you can understand why I feel that way, having seen the works of A.Q. Khan. It was a dangerous network that we unravelled. And the world is better for it, he added.
