Millions of people gathered at Tehran’s Grand Mosalla this week to attend the funeral of former Supreme Leader Ayatollah Ali Khamenei [1].

The massive turnout serves as a defiant signal from Iran toward the United States and Israel following the killing of the religious leader in the U.S.–Israeli war [3, 5].

The event is part of a weeklong series of ceremonies taking place in five cities across two countries [5]. The funeral follows a four-month interval since Khamenei was assassinated in early March 2026 [2].

Crowds at the Tehran site echoed anti-U.S. and anti-Israel chants. Reports on the size of the gathering vary, with some sources saying millions attended [1], while others noted hundreds of thousands were present [4].

The atmosphere was marked by intense hostility toward U.S. leadership. One unnamed performer at the funeral said, "I want Donald Trump dead" [4].

This event follows a period of extreme escalation in the region. On Feb. 28, 2026, an airstrike killed members of Khamenei's family [2]. The subsequent assassination of the Supreme Leader in March further strained diplomatic relations, leading to the current displays of public anger in Tehran.

Official ceremonies continue to move through the designated cities to allow mourners to pay their final respects to the former leader [5].

"I want Donald Trump dead"

The scale and tone of the funeral indicate that the assassination of Ayatollah Ali Khamenei has become a primary catalyst for Iranian nationalism and anti-Western sentiment. By transforming a period of mourning into a public demonstration of defiance, the Iranian leadership is consolidating domestic support and signaling that the U.S.–Israeli war has fundamentally altered the trajectory of their foreign policy.
