North Korea in final Uranium phase

North Korea has reportedly entered the final phase of uranium enrichment.



The North\'s state media are reported as saying that uranium enrichment tests have been successfully carried out and that the process is in the concluding stage.



If confirmed, the move would be in defiance of international pressure for the North to abandon its nuclear work.



The United Nations passed tougher sanctions after a nuclear test by Pyongyang in May.



Both that test and an earlier nuclear test by North Korea in 2006 were understood to have been plutonium-based warheads.
