Mourners from across the country, as well as high-ranking Iranian officials along with groups of foreign guests and ambassadors will take part in the commemoration ceremony.
Every year, large crowds of Iranians travel to Tehran from different parts of the country on this day to pay tribute to Imam Khomeini at his shrine.
Ayatollah Ruhollah Moussavi Khomeini, better known as Imam Khomeini, engineered Iran’s 1979 Islamic Revolution, which led to the overthrow of the US-backed Shah of Iran.
Born in 1902, he grew to become the iconic leader of the Iranian nation’s struggle in the 1970s against the centuries-old monarchical tyranny.
Imam Khomeini passed away on June 3, 1989, at the age of 87.
