TEHRAN, Jan. 14 -- Iranian President Hassan Rouhani said Tuesday that the "Geneva nuclear deal broke the sanction regime that had been imposed against the Iranians unfairly."

Rouhani made the remarks two days after Iran and the world powers agreed to start the implementation of the landmark nuclear deal on Jan. 20.

The Geneva deal means "powers" yielding to the demands of Iran, " the Iranian president said addressing a gathering in Iran's southwestern city of Ahvaz.

"By Geneva deal, the world accepted the peaceful nuclear technology of Iran which has been achieved through the hard work of the young Iranian students," he added.

An agreement was finalized between the P5+1 and Iran on Sunday on ways to implement the first-step Geneva agreement on Tehran's nuclear program.

In November, Iran and the P5+1 group reached an interim agreement whereby Iran would freeze part of its nuclear program in exchange for limited ease of sanctions which had hurt its economy.
