On Nov. 24, 2013, the United States, France, Britain, Germany, China and Russia reached a nuclear deal with Iran, following intense negotiations that took place over several days in Geneva.
Iran and six of the world's powers agreed on a "first step deal” that is meant to limit advancements in Iran's nuclear program in exchange for easing some of the economic sanctions that have deeply hurt Iran's economy.
According to the White House, the deal stipulates that Iran will commit to halt uranium enrichment above 5 percent and also to neutralize its stockpile of near-20 percent enriched uranium. The Islamic Republic has also committed to halt progress on its enrichment capacity. Iran will also halt work at its plutonium reactor and provide access to nuclear inspectors. - NBC News
