The head of the U.N. nuclear watchdog was meeting with officials in Iran on Saturday, days after it was revealed that the country had enriched particles of uranium to near weapons-grade, raising new alarm over its long-disputed nuclear program.
Rafael Mariano Grossi, the head of the International Atomic Energy Agency, declined to comment on his discussions during a press conference with the head of Iran's nuclear program, saying the delegation's work was still ongoing.
