‘Evidence Of Undeclared Nuclear Activities’ Discovered At Locations In Iran That Raise New Concerns: Report

International inspectors from the United Nations have reportedly found new evidence of nuclear activity in Iran that the nation has not reported—in violation of its international obligations — and that could be indicative of work on making nuclear weapons.

The U.N.’s International Atomic Energy Agency (IAEA) discovered the “new evidence of undeclared nuclear activities” at two sites during inspections last fall, The Wall Street Journal reported, according to multiple diplomats briefed on the situation. The two samples “contained traces of radioactive material” that they believe “could indicate Iran has undertaken work on nuclear weapons, based on where it was found.” The report did not state what specifically was discovered at the two sites.
