Iran has condemned a “provocative” IAEA resolution backed by the U.S., France, the UK, and Germany, escalating nuclear tensions. Tehran insists its uranium enrichment is for peaceful purposes, warning of a "firm response" if pressured further. Amid five rounds of indirect U.S.-Iran talks in Oman, Tehran is preparing a counterproposal, rejecting the current U.S. offer for lacking sanctions relief. As Western allies push for a halt, Iran stands firm, with Supreme Leader Khamenei calling enrichment rights “nonnegotiable.” The next round of talks is set for June 15 in Muscat.
