Scientist says Pakistan knew of Korea nuke deal

The claim is the most controversial leveled by Abdul Qadeer Khan, who in recent months has been agitating for an end to house arrest and backing off his 2004 confession that he was solely responsible for spreading Pakistan's nuclear arms technology to Iran, North Korea and Libya.

The retired scientist's comments could prove embarrassing for Pakistan, which has repeatedly denied the army or government knew about Khan's proliferation activities before it was reported uncovered in 2003.

His allegations also could become awkward for Washington in its support for Musharraf, who has been a key U.S. ally in the region but has seen his power and popularity at home slide over the past year from anger over his firings of judges and confrontations with Islamic extremists.

A spokesman for Musharraf rejected Khan's claims, calling them "all lies." But some Pakistani experts have long argued that Khan's network could not have operated without the knowledge of the country's pervasive intelligence agencies.

In a telephone interview with The Associated Press, Khan said a shipment of used P-1 centrifuges--which enrich uranium for nuclear warheads--was sent from Pakistan in a North Korean plane that was loaded under the supervision of Pakistani security officials.

Khan said that the army had "complete knowledge" of the shipment and that it must have been done with the consent of Musharraf, the army chief who seized power in a 1999 coup.

"It was a North Korean plane, and the army had complete knowledge about it and the equipment," Khan said. "It must have gone with his (Musharraf's) consent."

His allegations were first reported Friday by the Japanese news agency Kyodo.

Musharraf's spokesman, Rashid Qureshi, disputed Khan's charges. "I can say with full confidence that it is all lies and false statements," Qureshi said.
