UN nuclear chief says North Korea has close to six nukes

Asked by CNN if it was the IAEA's assessment that the North Koreans already have as many as six nuclear bombs, IAEA chief Mohamed ElBaradei said: "I think that would be close to our estimation."
"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 know -- we have read also that they have the delivery system."
