Iran has buried its assassinated former supreme leader, Ayatollah Ali Khamenei, following a week of mass funeral processions, rallies and mourning ceremonies. Khamenei was killed at the start of the US-Israeli war, but his burial was delayed by the ongoing conflict, during which several senior Iranian figures were also targeted and killed. The moment marks a significant transition for Iran's leadership at a time of heightened regional tension.

Khamenei has been succeeded as supreme leader by his son, Mojtaba, who has not appeared in public since he was reportedly wounded in the same attack that killed his father. The BBC's chief international correspondent, Lyse Doucet, examines how Iran's new leadership is likely to respond to the range of challenges now facing the country. The report was published by BBC News, which noted the burial came after days of nationwide mourning.
