TEHRAN - Qatar and the United States were committed to an agreement with Iran regarding the country's use of its unfrozen funds worth $6 billion, Qatari Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani said on Saturday.

The fund release process was advancing following the agreement between the central banks of Iran and Qatar, said the Qatari foreign minister during a phone call with his Iranian counterpart Hossein Amir-Abdollahian.

Iran's funds were released last year by South Korea as part of a prisoner swap agreement between Iran and the United States and were transferred to six Iranian accounts in two Qatari banks.
