The Iranian government is increasing pressure on anti-government protestors who are calling for change.
Clashes broke out between pro- and anti-government groups in central Tehran on Wednesday. It came 2 days after another clash between anti-government protesters and security troops left 2 people dead.
The Iranian government says it will hold large-scale rallies on Friday in Tehran and elsewhere to counter the anti-government demonstrations. The government is calling on Iranians to participate in the rallies.
Iranian clerics are demanding that the leaders of the recent anti-government protests be indicted. The country's prosecutor general has also said he may punish the pro-democracy leaders.
The opposition leaders are reacting sharply against the government's hard line stance.
Former prime minister Mir Hossein Mousavi and former parliament speaker Mehdi Karroubi issued statements in support of the anti-government protestors.
