Nuclear watchdog chief to meet top Iranian officials in Tehran on Sunday

The acting chief of the U.N. nuclear watchdog policing Iran's nuclear deal with major powers, Cornel Feruta, will meet senior Iranian officials in Tehran on Sunday, a spokesman for the International Atomic Energy Agency said on Friday.

"The visit is part of ongoing interactions between the IAEA and Iran," the spokesman said.

The trip comes before a quarterly meeting of the IAEA's 35-nation Board of Governors next week and after an IAEA report suggested Iran's cooperation with the agency was less than ideal, saying: "Ongoing interactions between the Agency and Iran ... require full and timely cooperation by Iran. The Agency continues to pursue this objective with Iran."
