Under an interim nuclear deal in November 2013, some of Iran's blocked funds were released by Asian buyers, including India. Indian companies have deposited 45 percent of their oil payments in a rupee-denominated account at United Commercial Bank, which Iran is allowed to use to buy goods not covered by sanctions, such as food and medicine.</div><div> </div><div>(Reuters)</div>
