S. Korea says: North Korea can make 7 nuclear bombs

South Korea estimates North Korea has enough plutonium to make as many as seven nuclear bombs, according to a Defense Ministry report. The communist nation is also working to make a small, lightweight nuclear warhead that can be mounted atop a ballistic missile, the ministry said in the internal assessment made public by Song Young-sun, a lawmaker from the main opposition Grand National Party. The assessment is based on a meeting of top South Korean military officials a day after the North's Oct. 9 nuclear test. The report says the North is believed to have extracted 110 pounds of high-grade plutonium, enough for up to seven nuclear weapons. The North can use its Russian-made bombers to drop the bombs, the ministry said, adding that the North has 82 Il-28 bombers at bases in Uiju and Jangjin. North Korea also has built a nuclear warhead weighing some two to three tons. To be mounted on a missile, the warhead would need to be less than one ton, the ministry said.
