Washington: The United States has said that Libya's stockpiles of mustard agent and uranium yellowcake, a potential ingredient for nuclear weapons, are secure and represent no threat.
State Department spokeswoman Victoria Nuland said US envoy Chris Stevens was in talks with Libyan rebels about their plans to assume control of a site in Tajjura where yellowcake is kept and a mustard agent storage site in Waddan.
Nuland was providing more elaborate information than that given by Washington on Wednesday, when Nuland and other officials said stockpiles of missiles and chemical weapons were secure.
"All sensitive elements of Libya's nuclear program, including everything that Libya received from the AQ Khan network, were removed in early 2004," Nuland told reporters.
"The last of the highly enriched uranium, the bomb-making fuel, was removed from Libya in 2009," she said.
She said Libya's supply of yellowcake is "safeguarded" at the Tajjura nuclear research facility.
"We are able, through our national technical means, to assert that we believe that it is secure and .... in any case, Libya doesn't have the means right now to turn yellowcake into anything dangerous," she added.
The now fugitive Libyan strongman Moamer Gaddafi's stockpile of mustard agent meanwhile is "now stored at the Waddan Ammunition Reservation," Nuland said.
"It is inside massive steel containers within heavy bunkers. These bunkers were sealed by the Organization for the Prohibition of Chemical Weapons, the OPCW," Nuland added.
"Our judgment is that they remain secure," she said, adding the chemicals are not ready to be mounted on weapons.
"They can't be converted on a dime. And they're in these massive drums inside a heavy bunker. And we are able to monitor the security with national technical means," she added.
The State Department and Pentagon said on Wednesday that Libya's stockpiles of missiles and chemical weapons were "secure" but that an arsenal of thousands of shoulder-launched missiles remained a cause for concern.
