Iran has warned European powers that it may respond to the potential reactivation of the UN snapback sanctions mechanism by significantly increasing its uranium enrichment levels to 90%, reaching weapons-grade material. The Tasnim News Agency, affiliated with the Islamic Revolutionary Guard Corps, indicated that Iran could also use enriched uranium for military purposes and consider withdrawing from the Nuclear Non-Proliferation Treaty (NPT). Western diplomatic sources reported that during talks in Istanbul with representatives from Germany, France, and Britain, Iranian officials explicitly stated that Tehran would exit the NPT if the snapback sanctions were triggered. These developments come amid heightened tensions as Europe has warned of reimposing sanctions through the snapback mechanism in response to Iran's nuclear activities.
