In a confidential report, the International Atomic Energy Agency (IAEA) said that it had closed two safeguards-related inquiries with Iran. One was related to inspectors' discovery of uranium particles enriched to 83.7% purity at Iran's Fordow enrichment site earlier in the year. The IAEA said Iran's explanation that the particles were a byproduct of fluctuations in the enrichment process was "not inconsistent" with data reviewed by the Agency. The other inquiry was related to traces of man-made uranium found at Marivan, a site linked to Iran's early-2000s secret military nuclear program. The IAEA said Iran's claim that the uranium traces were left by instruments used at a mine operated in the area by a foreign entity in the 1960s and 70s was "possible." The Agency also reported that it had re-installed enrichment monitoring devices at Fordow and Natanz and had installed cameras at a centrifuge workshop in Isfahan.

The Russian state-owned bank VTB opened a representative office in Iran. The Iranian government is also planning to allow consumers to use Russia's Mir card payment system within Iran.

U.S. Special Envoy for Yemen Tim Lenderking said that Iran is still supplying arms and drugs to Yemen despite a March agreement restoring diplomatic relations between Iran and Saudi Arabia. The conflict in Yemen is widely seen as a proxy fight between the two regional rivals.
