Iran said on Monday that reviving a 2015 nuclear deal is possible if Western powers take a political decision to resolve three remaining issues, as indirect negotiations between Tehran and Washington enter a crucial stage.
Iran's foreign ministry spokesman identified the remaining outstanding issues as: the extent to which sanctions would be rolled back, providing guarantees that the United States will not quit the pact again, and resolving questions over uranium traces found at several old but undeclared sites in Iran.
