International monitors are watching Iran’s fast-expanding nuclear program with growing alarm, as Tehran refuses to extend an expired inspections pact and insists the experts must trust that it’s accurately documenting uranium-enrichment activities.

Iran claims it’s still preserving data captured by International Atomic Energy Agency monitoring equipment, the agency’s director general, Rafael Mariano Grossi, said in an interview in Rio de Janeiro. But officials won’t give his investigators access to it until Iran concludes stalled talks with world powers to restore a broader 2015 agreement that lifted sanctions.
