Tehran , Iran ( CNN ) -- As Tehran approaches the 30th anniversary of the Iranian hostage crisis , in which dozens of Americans where held against their will for 444 days , the Islamic republic is firmly warning against reformists taking to the streets to protest the government . Still reeling from the massive demonstration that followed the country 's disputed presidential election , Iran on Wednesday will commemorate November 4 , 1979 , when a group of Islamist students seized the U.S. Embassy in Tehran , taking 53 hostages and effectively ending diplomatic relations with the United States . While the government will allow the `` faithful '' to celebrate the anniversary of the embassy seizure , those who `` intend to gather illegally and spread lies among people who gather to peacefully participate ... will be held responsible for their actions , '' said Ahmad Reza Radan , head of Iran 's security forces , according to the semi-official Iran Student Correspondent Association . The government of Iran arrested more than 1,000 people in a massive crackdown after the June 12 election , in which incumbent President Mahmoud Ahmadinejad was declared the overwhelming winner . In the aftermath of the fallout , the government accused several reformists , including opposition candidates Mehdi Karrubi and Mir Hossein Moussavi , of spreading anti-government propaganda and fueling the anger among the public . Despite warnings from Iran 's hardline leaders , the reformists have largely refused to back down . They released the names of 72 protesters they say were killed in the unrest that followed the election -- more than double the government 's official number . Karrubi , a former parliamentary speaker , has been especially vocal about the claims of detainee rape . He publishing a firsthand account of one alleged victim on his Web site last month . He has been scorned by government hard-liners , whose credibility and legitimacy have been publicly questioned since the elections . On Wednesday , Islamic authorities tried to pre-emptively silence anti-government demonstrations and rhetoric .
