Thousands of people gathered at the Mosalla Great Mosque in Tehran to begin a six-day funeral ceremony for former Supreme Leader Ali Khamenei. The event follows his death resulting from an airstrike launched by American and Israeli forces at the start of their military conflict with Iran. Donald Trump expressed shock upon learning that tens of millions of Iranians are mourning the leader. Trump admitted he previously believed the population hated Khamenei. Tehran has officially entered its second day of public mourning to honor the former leader. The ceremonies were originally delayed from February following the military strike. This mass display of grief contrasts with previous expectations of public unrest.
