The trials began today of prominent moderates arrested shortly after Iran's disputed June presidential election and charged with fomenting unrest, Iranian media reported.
The official IRNA news agency quoted the indictment as saying the charges against the defendants also included acting against national security by planning unrest, participating in the "Velvet Revolution", attacking military and state buildings and conspiring against the ruling system.
Velvet Revolution was used to describe the non-violent 1989 revolution in Czechoslovakia which overturned communist rule.
Under Iran's Islamic law, acting against national security, a common charge against dissenting voices in Iran, could be punishable by the death penalty.
The June 12th vote plunged Iran into its biggest internal crisis since the 1979 Islamic revolution and exposed deepening divisions in its ruling elite.
Moderate defeated presidential candidates Mirhossein Mousavi and Mehdi Karoubi say the vote was rigged in favour of hardline President Mahmoud Ahmadinejad.
The authorities deny the charge and Iran's Supreme Leader, Ayatollah Ali Khamenei, has endorsed Mr Ahmadinejad's re-election.
"The trial of some of those accused of being involved in post-election unrest started this morning," Fars news agency reported.
Those on trial included prominent reformers such as former vice president Mohammad Ali Abtahi, former deputy foreign minister Mohsen Aminzadeh, former government spokesman Abdollah Ramazanzadeh, former senior lawmaker Mohsen Mirdamadi and former Industry Minister Behzad Nabavi, Fars reported.
The hardline semi-official news agency said at least four prominent reformers now said that the vote was not rigged.
"Former vice-presidents Mohammad Ali Abtahi and Mohsen Safai-Farahani, former Industries Minister Behzad Nabavi, (Iranian-Canadian journalist) Maziar Bahari and former deputy interior minister Mostafa Tajzadeh have confessed their claims about the vote violation were baseless," Fars reported.
On Thursday thousands of pro-reform demonstrators gathered to mourn those killed in post-election unrest, in a show of defiance of the authorities upholding Ahmadinejad's victory. Riot police fired tear gas and arrested some protesters.
A police official told the semi-official ILNA news agency yesterday that 50 protesters had been arrested but said "many of them have been released later".
Rights groups say hundreds of people, including senior pro- reform politicians, journalists, activists and lawyers, have been detained in Iran since the election.
Iran's top judge, Ayatollah Mahmoud Hashemi-Shahroudi, ordered the judiciary on Monday to follow the cases of detained protesters.
