Following the death of Iran's Supreme Leader Ayatollah Ali Khamenei due to strikes by the US and Israel, reactions from around the world have been varied and significant. In Tehran, celebratory scenes emerged as some citizens took to the streets expressing joy through music and fireworks, although these celebrations were muted in scale, likely influenced by the fear permeating Iran after the violent suppression of mass protests in January.

Conversely, thousands of mourners also gathered on the streets of Tehran, dressed in black and congregating in Revolution Square, exhibiting grief with calls for retribution against the US and Israel. The presence of Iranian flags and portraits of Khamenei highlighted the deep emotional and political divide within the nation, where the response to the death of its leader was marked by both joy and sorrow.

Iranian authorities have announced a 40-day mourning period following Khamenei's death, with President Masoud Pezeshkian describing the circumstances of his demise as tantamount to a declaration of war. This complexity reveals the tension within Iran as well as among international observers, signaling potential repercussions in an already fragile geopolitical landscape.
