Describing Pakistan's rogue nuclear scientist A Q Khan as "probably the world's greatest proliferator," the US has said that the damage he has caused is "incalculable."
"With respect to A Q Khan, there's no doubt he is probably the world's greatest proliferator. The damage that he's done around the world has been incalculable," Secretary of State Hillary Clinton said on Wednesday in response to a question from a lawmaker at the House Committee on Foreign Affairs.
"We have made it very clear that the network had to be dismantled and it was. There are people who were connected with A Q Khan who are out of business or who were imprisoned. And there are ongoing efforts to continue to obtain useful information," Clinton said.
Khan, 73, was slapped with US sanctions along with those on his network. He was put under house arrest in 2004 by then Pakistan President Pervez Musharraf after he admitted having passed nuclear know-how to North Korea and Iran.
Khan was released by a Pakistani court from house arrest in February this year.
