Opposition members went on roof tops late Wednesday and shouted Allah-u-Akbar ("God is greatest") in protest -- echoing similar cries after the disputed June election as well as anti-shah protests more than three decades ago.

Calls for calm as streets will be filled for the anniversary of 1979 Islamic Revolution

Iranian security forces were deploying in strength in Tehran tonight to head off what opposition supporters hope will be massive street protests to challenge the regime as its celebrates tomorrow's anniversary of the 1979 Islamic Revolution.ot" since June, John Limbert said. "The … international community can bear witness to what is going on there."
Mir Hossein Mousavi, leader of the green movement, has called on supporters to behave peacefully during state-sponsored events including a speech by the hardline president, Mahmoud Ahmadinejad, which is likely to be attended by tens of thousands of government loyalists. Green supporters are being asked to chant: "Death to no one, long live everyone" – a reference to the slogans of "Death to America" and "Death to Israel" that are traditional staples of Iran's revolutionary political culture.
But with reports of another death sentence handed down to a rioter, arrests of opposition activists and large numbers of Revolutionary Guards and Basij militia arriving in Tehran from outlying areas, nervousness was mounting last night.
"We are closely watching the activities of the sedition movement, and several people who were preparing to disrupt the 11 February rallies were arrested," the Fars news agency quoted the city's police chief, Esmail Ahmadi-Moghaddam, as saying. "If anyone wants to disrupt this glorious ceremony, they will be confronted by people and we, too, are fully prepared."
Ayatollah Ali Khamenei, Iran's supreme leader, warned this week that the country's enemies would get a "punch in the mouth" if there were new protests. The ILNA news agency said one of nine unnamed "rioters" arrested after demonstrations in December had been sentenced to death and the rest to prison terms. Last month, two young men described as terrorists were hanged after being convicted of the crime of being "enemies of god".
Official plans to deal with the latest bout of internal unrest coincide with mounting international tensions after the US president, Barack Obama, accused Iran of trying to build a nuclear weapon and warned it would face new sanctions within weeks. The regime accuses opposition supporters of serving foreign interests.
Shirin Ebadi, the Iranian Nobel Peace laureate, warned that her country faced catastrophe if repression did not end. "A recurrence of the recent months' events, the continuation of repressive policies and the killing of defenceless people could bring about a catastrophe that may undermine peace and security in Iran, if not in the entire region," she told the UN human rights council in Geneva.
Today's 31st anniversary of the 1979 revolution is the most important date in the official calendar. But events will take place behind a virtual media blackout, with the few foreign journalists in Tehran operating under severe restrictions, including being ordered to report only on pro-government rallies. Some 65 Iranian journalists are under arrest, and internet communications have been largely shut down. Disruption has also been reported to text-messaging services used by protesters to organise demonstrations.
Loudspeakers have been mounted along the route to the capital's Azadi (Freedom) square, where Ahmadinejad is to speak, to drown out opposition slogans. Protesters were advised to use whistles. Mousavi has not announced his plans but Mehdi Karroubi, another defeated presidential candidate, said today he would take part and urged his supporters to "demand their legal rights with their silence". Mohammed Khatami, the former reformist president, called for support for "the common aim of defending the revolution and the people's rights as the main possessors of the revolution".
The opposition claims that Mousavi, a former prime minister, was the rightful winner of June's presidential elections and that Ahmadinejad's victory was fraudulent. Sporadic street protests have persisted since then, despite a crackdown in which scores have been killed and hundreds arrested. In the most recent flare-up, eight people died in clashes between police and protesters on 27 December when opposition supporters used the annual Shia Ashura ceremonies to stage anti-government rallies. Two opposition leaders, Mohsen Aminzadeh and Behzad Nabavi, were jailed this week.
In Geneva, a senior US official said he hoped a UN debate next week on Iran would include investigations of the arrest of opposition leaders and alleged abuses of detainees. People in Iran have been "gassed, arrested, beaten up and sh
