Overview

• A confidential IAEA report shows Iran increased its 60 percent enriched uranium from 274.8 kg in February to 408.6 kg as of May 17, placing it one technical step from weapons‐grade levels.
• IAEA Director General Rafael Mariano Grossi reiterated the agency’s demand for full cooperation after inspectors detected uranium traces at multiple undeclared locations in Iran.
• The stockpile’s rapid growth alarms experts because about 42 kg of 60 percent enriched uranium is theoretically enough to produce one atomic bomb if taken to 90 percent purity.
• European members of the IAEA board may consider reimposing snapback sanctions under the 2015 nuclear deal’s provisions in response to Tehran’s escalation.
• Israel’s prime minister’s office called the report proof of Iran’s weapons ambitions, while Tehran insists its program is peaceful and US negotiators press for a new pact.
