North Korea preparing for third nuclear test

North Korea has almost completed preparations for a third nuclear test and has the capacity to carry it out soon, a senior source with close ties to Pyongyang and Beijing told Reuters.Soon. Preparations are almost complete, the source said when asked whether North Korea was planning to undertake a nuclear test.North Korea said last week it was ready to retaliate in the face of international condemnation over this months failed rocket launch, increasing the likelihood the hermit state will push ahead with a third nuclear test in defiance of U.N. sanctions.The source has correctly predicted events in the past, telling Reuters about North Koreas first nuclear test in 2006 days before it took place.This is the first time an official with knowledge of Pyongyangs intentions has confirmed the test is set to happen.South Korean newspapers have quoted officials in Seoul as saying the test could take place as early as in two weeks.The source did not specify whether the test would be a third test using plutonium or whether Pyongyang would use highly enriched uranium.Many analysts expect that North Korea will for the first time try a nuclear device using highly enriched uranium, something it was long suspected of developing but which it only publicly admitted to about two years ago.Defence experts say that by successfully enriching uranium, to make bombs of the type dropped on Hiroshima nearly 70 years ago, the North would be able to significantly build it up stocks of weapons-grade nuclear material.It would also allow it more easily to manufacture a nuclear warhead to mount on a long-range missile.
