Iranian lawmakers have proposed a bill that would scrap a landmark 2013 interim nuclear agreement if new sanctions are imposed.

The state-run IRNA news service on Wednesday quoted lawmaker Hossein Naqavi Hosseini as saying that some 80 out of 290 parliamentarians support the bill. It would still need to be put to a debate, then a vote, and then be approved by a constitutional body.

U.S. senators are pushing to impose new sanctions against Iran if a final nuclear accord is not reached by July 6. But President Barack Obama has said that would “all but guarantee” the failure of delicate international negotiations.

Western nations have long suspected Iran’s nuclear program is secretly aimed at producing an atomic weapons capability. Tehran insists the program is entirely devoted to civilian purposes.
