NAIROBI , Kenya ( CNN ) -- Iran 's trial of more than 100 people who it has linked to post-election unrest is a `` sign of weakness '' and shows that the Islamic republic `` is afraid of its own people , '' U.S. Secretary of State Hillary Clinton told CNN Thursday . Iran is `` afraid of the truth and the facts coming out , '' Secretary of State Hillary Clinton said . `` It is a show trial , there 's no doubt about it , '' Clinton told CNN 's Fareed Zakaria in a wide-ranging interview to be broadcast on his `` GPS '' program Sunday . `` It demonstrates I think better than any of us could ever say that this Iranian leadership is afraid of their own people , and afraid of the truth and the facts coming out . '' Clinton spoke to Zakaria during her visit to Africa . Those on trial include Newsweek reporter Maziar Bahari , who has dual citizenship in Iran and Canada , and Kian Tajbakhsh , an Iranian-American scholar . The trial , which began over the weekend , is scheduled to resume Saturday , according to Iran 's semi-official Fars News Agency . This week , the State Department issued a statement expressing deep concern for Tajbakhsh . `` Given that the charges facing Mr. Tajbakhsh are without foundation , we call on Iran 's leadership to release Mr. Tajbakhsh without delay , '' State Department spokesman Robert Wood said Tuesday , reading a prepared statement . `` He has played absolutely no role in the election and poses no threat to the Iranian government or its national security . '' Wood said Tajbakhsh has not been provided an attorney , which he is entitled to , and warned Iran that `` the world is watching what is happening in Iran and will bear witness . '' Speaking on Thursday , Clinton said the United States also has `` expressed our concern about Mr. Bahari 's confinement and trial '' to Canada 's government , and offered its help . All of those on trial in Iran -- who include Iranian journalists and supporters of the opposition -- have been charged for their alleged roles in protests that followed last month 's disputed presidential election . The June 12 election gave President Mahmoud Ahmadinejad a second term in office , but it also sparked a massive opposition movement that has regularly protested against the Iranian leadership and has shaken the foundation of Iran 's Islamic theocracy . Those on trial will be placed into three categories , according to Fars : the `` plotters , intriguers , and planners of the riots '' ; `` the antagonists and those affiliated to foreign services '' ; and `` the opportunists , hooligans , and hoodlums who set ablaze , or destroyed private and public properties , and those that have had hands in disturbing public security . ''
`` It is a show trial , there 's no doubt about it , '' Clinton told CNN 's Fareed Zakaria . Among the accused is journalist Maziar Bahari , a dual citizen of Iran and Canada . Iranian-American scholar Kian Tajbakhsh also is charged with crimes . Interview with the secretary of state will be broadcast on `` GPS '' Sunday .
