Hundreds of thousands of Iranians rally to mark the anniversary of the 1979 Islamic Revolution

Iranians rally for 31st anniversary of revolution

TEHRAN, Iran — Hundreds of thousands of Iranians gathered Thursday in a central Tehran square to mark the 31st anniversary of the revolution that created the Islamic republic as security forces dispersed nearby anti-government protests.

Tehran residents also reported Internet speeds dropping dramatically and e-mail services such as Gmail being blocked in a common government tactic to foil opposition attempts to organize.

State television showed images of thousands upon thousands carrying often identical banners marching along the city’s broad avenues toward the central Azadi, or freedom square, to attend a speech by Iranian President Mahmoud Ahmadinejad.

In Azadi Square itself, massive crowds waved Iranian flags and carried pictures of Ayatollah Ruhollah Khomeini, the founder of the Islamic state, and his successor as supreme leader, Ayatollah Ali Khamenei.

The opposition has vowed to stage counter demonstrations, but eyewitnesses say police have deployed hundreds of forces in central Tehran to confront them.

Witnesses said that riot police fired the paint-filled balls after protesters began to chant opposition slogans in Sadeqieh Square, which is about a half-mile (one kilometer) from the huge pro-government gathering.

Witnesses say there were no apparent injuries among the several hundred protesters.

Iranian authorities again tried to squeeze off text messaging and Web links in attempts to cripple protest organizers. Internet service was sharply slowed, mobile phone service widely cut and there were repeated disruptions in popular instant messaging services such as Google chat.

But several Iranians reached by The Associated Press said some messenger services, including Yahoo!, and mobile phone texting were still sporadically accessible. Many Internet users said they could not log into their Gmail account, Google’s e-mail service, since last week.

“We have heard from users in Iran that they are having trouble accessing Gmail,” said Google in a statement. “We can confirm a sharp drop in traffic and we have looked at our own networks and found that they are working properly.”

Opposition Web sites reported that protesters have gathered in several places in Tehran to display green banners.

Foreign media were only allowed to cover the ceremonies in the square and the speech by Ahmadinejad, with photographers bussed to the site and then away. There is an explicit ban on covering opposition protests.

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.

Since the election that brought President Mahmoud Ahmadinejad to power, opposition protesters have repeatedly taken to the streets.

Iranian authorities are desperate to show the upper hand on the most important day of the nation’s political calendar. But the high-profile events — including a huge gathering in Tehran’s Azadi Square and other places across Iran — offers a chance for opposition groups to make another powerful statement of their resolve.

Anti-government Web sites and blogs have called for a major turnout and urged marches to display green emblems or clothes — the color adopted by the anti-government movement since June’s disputed presidential election.

The opposition leaders have promised to join street rallies, including the Green movement founder and former presidential candidate Mir Hossein Mousavi.

Iranian officials, however, have warned that any protests will be immediately crushed by security forces. At least eight people were killed in clashes during the last major opposition marches in late December.

In recent months, the opposition has built its street protest strategy around days of important political or religious significance in attempts to embarrass authorities. The tone of the rallies, however, has shifted from outrage over alleged fraud in President Mahmoud Ahmadinejad’s re-election to wider calls against the entire Islamic system, including Supreme Leader Ayatollah Ali Khamenei.

The last large-scale marches — held to coincide with a Shiite holy day in late December — brought the most violent battles with security riots since shortly after the June 12 election.
