White House worried Iran could develop nuclear weapon in weeks

The White House is worried Iran could develop a nuclear weapon in weeks, press secretary Jen Psaki said on Tuesday, after Secretary of State Antony Blinken noted earlier in the day the country has accelerated its nuclear program.

"Yes it definitely worries us," Psaki said, adding the time needed for Iran to produce a nuclear weapon is down from about a year.

Earlier, Blinken said the US still believes a return to a nuclear deal is the best path with Iran, amid a prolonged standoff in talks. Facing criticism of the deal during an appearance before Congress, Blinken called the 2015 agreement imperfect but better than the alternatives.
