After a week of heavy pressure on the administration of moderate President Hassan Rouhani and senior members of Iran’s nuclear negotiating team, the Council for Monitoring the Joint Comprehensive Plan of Action (JCPOA) held a meeting on Dec. 7 to discuss Washington’s recent move to renew the Iran Sanctions Act (ISA).

Tasnim News Agency reported that after the meeting, the council announced that the renewal of sanctions would be “an evident violation of the nuclear deal.” Tasnim added, “The council has assessed different suggestions for Iran’s reactions, and will take necessary measures to counter all probable future scenarios.” The council provided no further details on Iran’s potential responses and possible measures.

The nuclear deal has once again made headlines since the US House of Representatives voted to renew the ISA on Nov. 15. The Senate approved the 10-year extension of the act on Dec. 1, sending the measure to the White House for President Barack Obama to sign the bill into law.

Tehran considers the renewal of the ISA to be a violation of the July 2015 JCPOA, which laid out a framework for lifting nuclear-related sanctions against Iran in exchange for curbs on the country’s nuclear program.
