Seoul admits extracting plutoniumSouth Korean officials are liaising
with the IAEA over the revelationsSouth Korea has admitted it extracted a small amount of plutonium - a key ingredient in nuclear bombs - in secret research conducted in the early 1980s.
The news comes just a week after Seoul said 0.2 of a gram of uranium was produced in 2000, by scientists who did not have government approval.
North Korea, in its first comment on that development, said it viewed it in the context of a regional arms race.
Seoul has been trying to get the North to give up its own arms programme.
A statement from South Korea's Science and Technology Ministry said investigations showed an "extremely small quantity of plutonium was enriched between April and May, 1982".
