The
European Union and
United States expressed concern on Thursday at Iran's holding of an inspector from the U.N. nuclear watchdog last week, with the U.S. envoy to the agency calling it an "outrageous provocation" that must have consequences.
Reuters first reported on Wednesday that
Iran had held the inspector and seized her travel documents in what appears to be the first incident of its kind since Iran's
nuclear deal with major powers was struck in 2015.
Iran confirmed that it prevented the inspector from gaining access to its main uranium-enrichment facility at Natanz.
