Large-scale rallies were held across the country on Wednesday to mark the 36th anniversary of the 1979 takeover of the US embassy in Tehran.
Each year on the same day, people in Iranian cities take to the streets to mark the occasion, with demonstrators in Tehran gathering outside the building of the former US embassy to chant slogans against the United States.
Thirty-six years ago on Nov. 4, a group of university students stormed the US embassy and held 52 Americans hostage for 444 days until January 20, 1981, IRNA reported.
The building was being used as a center of espionage aimed at toppling the Islamic Republic in its early days, following the 1979 Islamic Revolution.
This became evident from documents later found at the compound, thereby giving the embassy the name "Den of Espionage."
November 4 marks the National Day of Struggle Against Global Arrogance and is also known as Student Day in Iran.
Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei delivered a speech in a meeting with students in Tehran ahead of the occasion on Tuesday.
The Leader said the Islamic Republic's struggle against the hegemonic system, embodied by the United States, is driven by logic and lessons from the past rather than sentiment.
"Contrary to some claims, the struggle of the Islamic Republic and the Iranian people against arrogant powers is not an illogical or sentimental move. It is based on reason and historical experiences," he said.
Ayatollah Khamenei warned that lack of vigilance and a focus on domestic differences would be a "great mistake", giving Washington the long-sought opportunity to harm the Islamic Republic.
"Such a mistake should be avoided by learning from the past experiences," the Leader said, citing the US-orchestrated 1953 coup d'état leading to the overthrow of Mohammad Mosaddeq's democratically-elected government.
