The head of the U.N. nuclear watchdog says his agency estimates North Korea could have five or six nuclear weapons and any test carried out by Pyongyang could "open a Pandora's box." Mohamed ElBaradei, director-general of the International Atomic Energy Agency, was asked on CNN's "Late Edition" whether the agency's assessment was that North Korea now possesses as many as six nuclear bombs. "I think that would be close to our estimation," ElBaradei said. "We knew they had the plutonium that could be converted into five or six North Korea weapons," he said. "We know that they had the industrial infrastructure to weaponize this plutonium. We have read also that they have the delivery system." North Korea has not tested a nuclear device, but recent satellite images indicate Pyongyang may be making preparations for one, a Defense Department official said Friday.
