The IAEA said in a statement on Friday that acting director general, Cornel Feruta, "will travel to Tehran on Saturday for meetings with high-level Iranian officials on Sunday", Aljazeera reported.
"The visit is part of ongoing interactions between the IAEA and Iran," the statement said, adding that this included "the IAEA's verification and monitoring in Iran under the Joint Comprehensive Plan of Action", the official name of the 2015 nuclear deal with world powers.
On Saturday, according to Financial Tribune, Iranian officials announced details of the third round of cuts in nuclear commitments under JCPOA, which Iranian President Hassan Rouhani announced on Wednesday, and said it would affect "the field of research and development".
Feruta reported last week that Iran's stock of enriched uranium has significantly surpassed the limits set by the pact and that it has continued to enrich uranium at a higher purity grade than allowed.
