WASHINGTON (Reuters) - The United States believes Iran's breakout time to producing enough highly enriched uranium for one nuclear weapon is now "really short" and alarming, a senior Biden administration official told reporters on Friday.

The official, speaking on condition of anonymity, did not have a precise time for the breakout, which has been estimated to be a matter of months.
