* speaking of the usual suspects, meanwhile:
"A senior Pakistani official said that the US continued to press Islamabad for more information on Mr Khan’s network, "but we have told them in no uncertain terms that he is off-limits".and let's not forget this:
He insisted that Pakistan had shared all it knew with the US and the International Atomic Energy Agency (IAEA), as well as putting questions to Mr Khan on behalf of US investigators. Pakistan should be trusted with the investigation and anything else would be violation of national sovereignty, he added.
But Washington believes the Khan network may still be active. The US Congress has been told how Swiss police recently foiled a plot to ship 60 tons of specialised aluminum tubes — used for building parts of a centrifuge cascade to enrich uranium — through Europe to Pakistan.
According to Andrew Koch, a defence expert, this involved using a middleman in Britain who was not previously known to be a Khan associate. The tubes, which he said could have ultimately been sent to Khan network customers, were eventually seized in the UAE by government authorities."
"Over the past year Swiss officials have requested at least four times that the Bush administration share documents and evidence related to Khan's nuclear black market. But the United States has never responded.
Swiss officials maintain it needs U.S. assistance in order to convict three Swiss men accused of helping AQ Khan set up a secret Malaysian factory to make components for gas centrifuges.
Last week U.S. weapons expert David Albright testified before Congress and said, "I find this lack of cooperation frankly embarrassing to the United States and to those of us who believe that the United States should take the lead in bringing members of the Khan network to justice for arming our enemies with nuclear weapons.""
