Iran received the second installment of previously frozen oil assets under an interim nuclear deal with world powers, local media reported on Saturday.

The new funds, amounting to 4.5 million US dollars, was transferred to the account of Iran's Central Bank on Monday, reports said.

Under the nuclear deal reached in Geneva in late November last year, Iran is urged to freeze and scale back part of its nuclear program for a six-month period in exchange for a western sanction relief, including a gradual release of Iran's oil assets up to 4.2 billion US dollars.

Under the agreement, the funds are scheduled to be paid out in eight transfers which started with a 550-million-dollar payment by Japan on February 1.

The International Atomic Energy Agency has been tasked with monitoring Iran's nuclear developments. Its head, Yukiya Amano, confirmed on Monday that Iran had made sufficient progress in implementing its commitments in line with the schedule.
