U.S. Central Intelligence Agency Director Porter Goss claims that North Korea has enough plutonium to produce at least one or two nuclear weapons. Goss also said the North's present-day nuclear capabilities have heightened compared to the agency's 2002 assessment of the communist regime.

Goss made the allegations at a Senate Intelligence Committee hearing on Wednesday. The CIA director also that North Korea could resume missile tests at any time, including those of longer-range missiles capable of reaching the United States.

Goss spoke a week after North Korea publicly declared for the first time that it possesses nuclear weapons and that it was boycotting six-party talks designed to end its nuclear weapons programs.

The spy chief added that North Korea continues to develop, produce, deploy and sell increasingly sophisticated ballistic missile technology.

Goss did not speculate, however, as to whether North Korea's current nuclear technology would allow it to launch a nuclear-tipped missile.
