North Korea says it put forward a "bold proposal" at talks on its nuclear programme, but heard nothing new from the United States. The talks in Beijing ended amid mutual recriminations on Friday, after US officials said Pyongyang had admitted having nuclear weapons. President George W Bush earlier accused North Korea of using "blackmail", after the new claims about its nuclear programme emerged in Washington. But a North Korean foreign ministry spokesman said the US had "repeated its old assertion that the DPRK (North Korea) should 'scrap its nuclear programme before dialogue,' without advancing any new proposal at the talks".
