Iran's Supreme Leader Ayatollah Ali Khamenei has said world powers must lift international sanctions as part of a landmark nuclear agreement.
In remarks broadcast live on state television on September 3, Khamenei warned that "there will be no deal" if the sanctions are not lifted.
He said Iran would only partially comply with its commitments if the sanctions are merely suspended.
Under the July 14 agreement between Tehran and world powers, sanctions will be gradually lifted in return for Iran imposing curbs on nuclear activities, which the West suspects are aimed at making an atomic bomb.
Khamenei, who has the final say on all state affairs in Iran, also said he favored a parliamentary vote on the deal, which President Hassan Rohani has opposed.
A special committee set up by parliament has already begun reviewing the agreement.
