North Korea to End Nuclear Work

North Korea has agreed to declare and disable all its nuclear facilities by the end of this year, the US negotiator at talks with Pyongyang in Geneva said. Christopher Hill said details of the deal would be discussed at six party talks in China, later in September. North Korea tested a nuclear device last year, but has since agreed to a deal to shut down its program in return for economic and other aid. It has already shut down its main nuclear reactor at Yongbyon.
