US Secretary of State Tony Blinken said Thursday that it will “further complicate” efforts to salvage the 2015 Iran nuclear deal if Iran removes cameras that monitor its nuclear program and could lead to “a deepening nuclear crisis and further economic and political isolation for Iran.”

The head of the International Atomic Energy Agency said earlier Thursday that Iran will “basically” remove all cameras installed under the 2015 nuclear deal, after the country was censured earlier this week by the IAEA’s Board of Governors for not fully cooperating with the nuclear watchdog.
