The future of a deal between the US and Iran regarding Tehran's nuclear program remains uncertain, according to Rafael Mariano Grossi, head of the UN's atomic agency. While negotiations continue, Grossi views the ongoing dialogue as a positive sign of willingness to reach an agreement. The talks, mediated by Omani Foreign Minister Badr al-Busaidi, have seen five rounds so far, with the latest round concluding in Rome. The discussions aim to limit Iran's nuclear activities in exchange for lifting US sanctions. Tensions remain high, with threats from both the US and Israel regarding Iran's nuclear capabilities.
