The U.S. government has concluded that nearly half of Iran’s monthly earnings from crude oil exports are accumulating in accounts outside the country because of sanctions that restrict Tehran’s access to the money. The estimates, provided to The Associated Press by a senior U.S. official, are the latest indication that new sanctions imposed in February are deepening Iran’s economic distress and making it increasingly difficult to access billions of dollars in vital oil revenues. Since Rouhani’s election in June, there have been a number of indications the distress is deepening. (AP Photo/Ebrahim Noroozi, File)
