Celebrations erupt in Iran as Mojtaba Khamenei is appointed the country's new supreme leader, succeeding his father, who was killed in U.S. and Israeli strikes. Supporters praise him as a loyal defender of the Islamic Republic. The fifty-six‑year‑old cleric, long influential behind the scenes, is expected to shape Iran's war strategy. Backed by Russia and China, he faces strong hostility from the U.S. and Israel, while many Iranians fear his rise dims hopes for change.
