The funeral of Iran's former Supreme Leader Ali Khamenei concluded a week‑long period of mourning, rallies and mass processions, culminating with his burial amid a backdrop of ongoing conflict.

The death of the late Supreme Leader, whose murder coincided with the escalation of the US‑Israeli war, pushed Iran’s political landscape into uncertainty. Senior Iranian figures were targeted and killed during the same attacks that forced a postponement of the funeral ceremony.

The leadership mantle passed to Mojtaba Khamenei, the senior leader’s son, who has not been seen in public following an alleged injury incurred during the attack. His sudden rise to power places him at the centre of a nation battling war‑related security challenges and internal unrest.

BBC Chief International Correspondent Lyse Doucet examines how Iran’s new Supreme Leader may respond to several critical issues that loom large for the country. These include the continuation of the US‑Israeli conflict, the protection of Iran’s internal security, and the maintenance of the country’s political legitimacy.
