Iranian Supreme National Security Council Secretary Ali Shamkhani warned that “the JCPOA will die forever by circumventing [UN Security Council Resolution] 2231 and continuing Iran's illegal weapons sanctions”. Iran’s diplomatic spokesperson subsequently also underscored that “Iran will serve an appropriate and decisive response” if the UN embargo was extended, adding: “we are waiting to see the direction in which circumstances are going to develop, and will then act based on them and deliver a response”.
