The head of the U.N. nuclear watchdog agency on Monday pressed North Korea to come clean on its nuclear program, told Iran to suspend uranium enrichment and said U.N. inspectors should return to Iraq. In his annual speech to the U.N. General Assembly, Mohamed ElBaradei, director general of the International Atomic Energy Agency, said North Korea continued "to pose a serious challenge to the nuclear nonproliferation regime" and that the IAEA could not "provide any level of assurance about the non-diversion of nuclear material." U.S. officials say Pyongyang has one or two nuclear weapons already plus material for another six bombs. The latest crisis over North Korea's nuclear ambitions began in October 2002 when U.S. officials said Pyongyang had admitted to pursuing a secret uranium-enrichment program. North Korea now denies having such a program, and has demanded energy aid and diplomatic concessions in return for freezing an older, plutonium-based nuclear arms program. In Iran, ElBaradei said that the IAEA had made some progress but that Tehran needed to suspend all uranium enrichment-related and reprocessing activities as a confidence-building measure. --More 2245 Local Time 1945 GMT
