IAEA Director General Rafael Grossi told the Board of Governors that his discussions with senior Iranian officials in Tehran the previous day had “proved inconclusive”. He also reported that  “the repeated prolongation of the [February Iran-IAEA] agreement… is becoming a significant challenge to the Agency’s ability to restore this continuity of knowledge”, and indicated that denial of access to a facility in Karaj was “seriously affecting the Agency’s ability to restore continuity of knowledge at the workshop, which has been widely recognised as essential in relation to a return to the JCPOA”. He also updated the Board on safeguards concerns.
