Thousands of Iranians rallied in Tehran to mark the 39th anniversary of the US Embassy's acquisition, as Washington is preparing to resume all sanctions imposed under the 2015 Nuclear Arrangement.
The crowd said "Under the US" and "Death in Israel" during the fight in the Iranian capital on Sunday and state television said similar demonstrations were held in other cities and towns.
Zein Basravi of Al Jazeera, quoted by Tehran, said the crowd is "bigger" and "angry" during this year's celebration.
"It is related to the fact that the anniversary coincides with the deadline for the United States to resume sanctions lifted by the 2015 Nuclear Weapons Agreement," he said.
"But many of the Iranians we spoke said that this deadline is meaningless and that foreign investment is already afraid … and that economic losses have already been made."
Shortly after the Islamic Revolution in 1979, Iranian students fell to the US Embassy, taking 52 hostages for 444 days. The US broke off diplomatic relations in response to hostage taking.
In Iran, November 4 is also known as Student Day and National Day of Fight Against World Arrogance.
The government of Iran celebrates the embassy as a decisive blow against the United States every year, which supported the domineering of Shah Mohammad Reza Pahlavi.

The union of the embassy, widely known as the "Spy City," is now a cultural center.
US anger and mistrust is reviving after President Donald Trump's decision to withdraw from Iran's nuclear agreement with world powers despite Tehran's compliance with the deal, which was negotiated under the Obama administration.
In May, the Trump administration announced the restoration of sanctions against Iran. The first round came into force in August, while the second round of Iran's oil and gas, as well as its shipping and banking industries, will come into force on Monday 5 November.
Iran is already in a state of economic crisis and has seen sporadic protests in recent months as Iranian officials have tried to reduce their sanctions and their effects.
The US has stated that sanctions are not aimed at overthrowing the government but persuaded to radically change its policies, including its support for regional armed groups and the development of large-scale ballistic missiles.
Iranian leaders said the sanctions are aimed at overthrowing the government and ruled out negotiations with the Trump administration.
At a meeting Saturday, Iran's supreme leader, Ayatollah Ali Hammeni, portrayed sanctions as part of a long tradition of American hostility toward the Islamic Republic, which he said nevertheless prevailed.
