The United States has decided to end sanctions waivers allowing Russian, Chinese and European firms to continue work at certain Iranian nuclear sites, a US official and another source familiar with the matter said on Wednesday.
The sources, who spoke on condition of anonymity, confirmed a report in the Washington Post that said the decision applied to waivers involving Iran's Arak heavy water research reactor, provision of enriched uranium for its Tehran Research Reactor and the transfer of spent and scrap research reactor fuel out of Iran. The sources said the United States would extend a separate waiver covering Iran's Bushehr nuclear power plant for 90 days.
