based Institute for Science and International Security, show for the first time that North Korea has resumed some work on a nuclear reactor that could enable it to increase stocks of weapons-grade plutonium, an analyst said. The pictures also appear to confirm earlier reports that the North Koreans had unloaded and restocked a smaller plutonium-producing reactor at its Yongbyon nuclear complex, the analyst, Corey Hinderstein, told Reuters. Asked to comment on President George W. Bush's endorsement of Iran's right to civilian nuclear energy, Hill said: "I think the president's words speak for themselves. "But I think the main issue here with the DPRK is we put together a comprehensive package to deal with the issue here and they've chosen to focus on something that is not in the package." The United States, which once described North Korea as part of an "axis of evil" along with Iran and pre-war Iraq, insists that Pyongyang dismantle all nuclear programmes verifiably and irreversibly, after which it could expect energy aid and security guarantees. --More 1117 Local Time 0817 GMT
