VOA - British Prime Minister Gordon Brown has offered1 international help for Iran to develop a civilian nuclear power industry. But, he says the offer is linked to the Iranian government ending its uranium enrichment2 program. Mr. Brown spoke to an international conference in London. He said the Iranian nuclear program has become a serious threat3 because of the government's refusal to end enrichment activities. But, he also said, “The world must find ways to help nations without nuclear programs to meet their energy needs and cut production of industrial gases.â€
