U.S. Secretary of State Antony Blinken considered Iran's announcement of its intention to start enriching uranium at 60% as a "provocative" step.
In a press conference at NATO headquarters, Blinken noted that this move raised questions about Tehran's seriousness in the nuclear talks in Vienna.
He said, "while Washington has demonstrated its seriousness to return to the 2015 nuclear accord between Tehran and world powers, Iran was yet to show such purpose."
It is worth mentioning that, Deputy Foreign Minister of Iran Abbas Araghchi told the official Iranian media, Tuesday, that Tehran will start on Wednesday enriching uranium by 60%.
He also revealed that Iran will install 1000 advanced centrifuges (its capacity is 50% higher than the current devices) in the Natanz nuclear facility, as well as replace the “destroyed machines” as a result of an explosion that occurred on Sunday in this nuclear complex in central Iran.
