The thirty-second anniversary of the death of Ayatollah Ruhollah Khomeini, the leader of the 1979 Revolution, first Supreme Leader of Iran and founder of the Islamic Republic, occurred today. The day is a large public holiday which ordinarily involves a procession to his grave at the Imam Khomeini Shrine in South Tehran. His successor, Supreme Leader Ali Khamenei, addressed the nation, saying that Khomeini considered voting a religious duty and, under certain circumstances, not voting a terrible sin.
