VIENNA (Reuters) - Progress has been made towards answering suspicions North Korea tried to enrich uranium for atom bombs but the issue is "by no means" solved, the chief U.S. negotiator on Pyongyang's nuclear disarmament said on Wednesday.
Christopher Hill was speaking after talks with Mohamed ElBaradei, director of the watchdog International Atomic Energy Agency (IAEA) which has monitors in North Korea verifying the process to disable Pyongyang's nuclear weapons programme.
