WASHINGTON (Reuters) - The United States' patience with Iran on returning to discussions over the 2015 nuclear deal is "not unlimited," State Department spokesman Ned Price said on Wednesday.

Iran has not formally responded to a U.S. offer last week to talk with Iran in a joint meeting with the countries that negotiated the deal.
