Iran has cancelled the accreditation of an international nuclear inspector who was recently prevented from entering a nuclear facility.
For more on this and other news from around the world, let's turn to our Kim Da-mi.
Da-mi, this incident is the first of its kind since the Iran nuclear deal was signed in 2015.
Right Mark, like you said, Iran insists that it blocked an unnamed IAEA inspector from accessing its Natanz site last week because she may have been carrying "suspicious material."
Iranian ambassador Kazem Gharib Abadi confirmed this at an IAEA meeting held in Vienna on Thursday.
According to the ambassador, an alarm went off while the inspector tried to enter the facility.
Abadi then underlined that any behavior that violates security and safety of Iran's nuclear sites is not be acceptable just like it wouldn't be in other IAEA member countries.
Iran added that the inspector later left the country without completing her visit.
The IAEA, however, disagrees with Tehran's account, adding that the inspector was also temporarily prevented from leaving Iran.
The European Union and the U.S. expressed deep regret, calling the inspector's detention an "outrageous provocation."
Just days after the episode, Iran resumed uranium enrichment at its underground Fordow facility, transforming it into an active nuclear site.
