A senior Iranian official is accusing the US of undermining the nuclear deal with his country.
Reza Najafi cites US comments indicating that any future attack on Tehran's atomic program would be more efficient than before because the accord would result in greater insight about potential targets.
The July 14 deal foresees increased overview of Iran's nuclear activities by the U.N.'s International Atomic Energy Agency. Najafi, the chief Iranian delegate to the IAEA, quotes White House spokesman Josh Earnest as saying that if U.S. or Israeli military action were needed in the future, it would be improved "because we'd been spending the intervening number of years gathering significantly more detail about Iran's nuclear program."
Najafi, in a July 24 letter posted to the IAEA website, called Earnest's statement "outrageous."
