Iran has received the fourth and fifth installments of previously frozen assets under an interim nuclear deal with world powers, the Central Bank of Iran (CBI) announced on Thursday. The installments, amounting to 1 billion U.S. dollars, have been deposited to the account of the CBI in the Central Bank of United Arab Emirates, according to the report. The Islamic republic "can use the money now," the CBI statement said without further elaboration. The release of parts of Iran's assets by the United States comes following a recent report from the International Atomic Energy Agency that Iran has completed some of its obligations, as stipulated in the deal it reached with world powers in November last year. The United States has now released 2.55 billion U.S. dollars to Iran since February. Under the deal with the U.S., Britain, France, China, Russia and Germany, Iran would halt part of its controversial nuclear program in exchange for an easing of sanctions that had crippled its economy.
