The International Atomic Energy Agency says starting on Tuesday Iran will stop allowing snap inspections to be conducted on the country's nuclear sites, but will continue to permit the agency to carry out necessary verification and monitoring activities for the time being.
The IAEA issued a statement after its head, Rafael Grossi, met the chief of the Atomic Energy Organization of Iran, Ali Akbar Salehi, in the country on Sunday.
The statement says that Iran will "stop the implementation of the voluntary measures as envisaged" in the 2015 nuclear accord with world powers.
It also says the two sides agreed to a "temporary bilateral technical understanding...whereby the IAEA will continue with its necessary verification and monitoring activities for up to 3 months."
Grossi spoke to reporters at an airport upon his return to Vienna. He said that Iran will start to offer "less access" to its nuclear facilities.
Meanwhile, the Atomic Energy Organization of Iran says it will store data on nuclear facility activities and provide them to the IAEA, only if the US removes its economic sanctions against Tehran. It has threatened to delete the records, if the sanctions are not lifted.
