Iran began a week-long funeral ceremony on July 4, 2026 [4], for the late Supreme Leader Ayatollah Ali Khamenei in Tehran.

The ceremonies mark a volatile transition for the Islamic Republic following the death of its highest authority during a conflict with the U.S. and Israel. The event serves as both a national mourning period and a platform for the state to signal its intent for military escalation.

Crowds gathered primarily at the Imam Khomeini Mosalla Grand Mosque to pay their respects. Reports on the size of the gathering vary, with some sources citing hundreds of thousands of mourners [1], while others estimate the number in the millions [2].

Khamenei, who was 86 at the time of his death [3], was killed in February 2026. His death resulted from an airstrike that initiated a broader war launched by the U.S. and Israel.

Iran's intelligence ministry, led by Ali Shamkhani, used the occasion to pledge that the state would avenge the blood of the late leader. The ministry's vow of retaliation comes as the country prepares for the final burial scheduled for July 9, 2026 [5].

The funeral rites are expected to continue throughout the week. This period of mourning is occurring against the backdrop of ongoing hostilities and a heightened state of alert across the region.

Iran's intelligence ministry pledged to avenge the blood of the late leader.

The funeral of Ayatollah Ali Khamenei is more than a religious rite; it is a strategic political mobilization. By framing the ceremonies around a vow of vengeance, the Iranian intelligence ministry is consolidating domestic support and signaling to the U.S. and Israel that the death of the Supreme Leader will serve as a catalyst for further aggression rather than a moment of diplomatic opening.
