Iran ramps up uranium production, throwing 'a brick on the accelerator' to nuclear threshold

Iran has recently quadrupled its uranium production, a spokesperson for the nation's atomic energy agency says. The nation has stopped complying with key parts of the 2015 Iran nuclear deal after the Trump administration ratcheted up pressure on the Islamic Republic. Iran would have eventually exceeded caps on uranium stockpiles, but it is now racing toward the threshold, a former U.S. sanctions official says.
