In Tehran, demonstrators marched to the former US embassy complex and gathered in front of it, waving flags and banners with anti-US and anti-western slogans.
The marchers also chanted slogans against the United States and Israel.
The United States cut diplomatic relations with Iran in 1980 after a group of Iranian students captured some 60 US diplomats in 1979. In the hostage crisis, 52 of the US diplomats were held in captivity for 444 days.
On Friday, the gathering in front of the former US embassy in Tehran ended with the issuance of a statement which called for resistance against "the US and Western policies against the regional states and the Islamic republic."
The statement condemned "the US plots" against the "nuclear rights" of Iran and against the Syrian government and nation, saying that Iranians consider the United States as the main enemy of the country.
The statement also slammed a movie produced in the West that insults the Islamic values and the prophet of Islam, Mohammed.
Tehran: Thousands of Iranians on Friday held rallies nationwide to mark the anniversary of "the seizure of the US embassy in Tehran" by Iranian students 33 years ago.
