The United States is stepping up diplomatic pressure on Iran and has proposed referring the issue to the UN Security Council over Tehran's obstruction of inspectors. According to Sina Finance, inspectors still cannot verify the location of Iran's stockpile of near-weapons-grade enriched uranium.
The move is expected to be taken up at this week's International Atomic Energy Agency board meeting in Vienna. According to Sina Finance, since Israel began airstrikes on Iran in June 2025, Iran has blocked the UN nuclear watchdog from inspecting its uranium stockpile for 15 consecutive months.
A copy of a two-page document shows the U.S. proposal calls on Iran to urgently correct its noncompliance and allow inspections to ensure nuclear material is not diverted. According to Sina Finance, IAEA Director General Rafael Grossi said on Monday that there was no contact and no information, and that Iran would not cooperate until some agreement was reached in broader political talks.
According to Sina Finance, Grossi told diplomats last week that the agency lacked information on the nuclear material and could not access the relevant facilities for inspections, calling it a proliferation concern. He said Iran needed to allow inspectors back to the facilities with the utmost urgency.
U.S. President Donald Trump has repeatedly said the current military action is aimed at preventing Iran from developing nuclear weapons. According to Sina Finance, Trump said on September 4 that the United States was considering another strike on a deeply buried nuclear facility and that it might strike Fordow soon.
