Claims the Financial Times:
Iranian security forces clashed with protesters as hundreds of thousands marched in Tehran on Monday in the biggest rally by the opposition Green Movement for more than a year.
Hmmm – "hundreds of thousands"?
A Tehran Bureau blog entry, a private endeavor, taken over by PBS after the 2009 election protests in Iran, has this anonymous account:
10:30 p.m. From a Tehran Bureau correspondent:
It was amazing today. About 350,000 people showed up. …
Hmm again. After reviewing many video clips (here, here and here) and pictures of the event I find those numbers totally unbelievable. Crowds of a few hundred people and in one case maybe some single digit thousand are visible in the 30+ video clips I reviewed. Those people are mostly student age folks chanting in the streets and burning a few trash cans. There is no evidence of any bigger demonstration.
That observation somewhat fits with the BBC report from a reporter on the ground:
Riding on the back of a motorbike, holding my mobile to take video footage, I went to central Tehran on Monday afternoon.
…
Thousands of people made their way amicably and silently towards the square, most of them young.
…
Riot police began to disperse the crowd before they even started the rally.
Reuters says:
Thousands of Iranian opposition activists rallied …
AFP has no own number but reports:
Websites and witnesses said thousands of opposition supporters had taken to the streets …
AP writes:
Tens of thousands of protesters clashed with security forces along some of Tehran's main boulevards, …
The New York Times only has a U.S. based source:
Numbers were hard to assess, given government threats against journalists who tried to cover the protests. Aliakbar Mousavi Khoeini, a former member of Parliament now living in exile in the United States, said that 20,000 to 30,000 people had taken part across the country.
Al Jazeera also goes with "thousands".
To reliably guestimate "hundreds of thousands" one would have to either measure a long tight march or have a decent top-view of the event. There is nothing in the FT piece that makes one believe that the reporters actually eye-witnessed or personally observed the rally at all. The number seems to have been plugged from hot air.
Update:
The Washington Post is doing some funny math. Today:
In Tehran, large crowds of protesters defied tear gas to march down a major thoroughfare, chanting "Death to the dictator." It was the biggest demonstration in the Iranian capital since the government effectively crushed the opposition movement in December 2009.
The crowds, which numbered in the tens of thousands, …
"The biggest since 2009." But only four days ago the same paper reported:
Hundreds of thousands of government supporters massed Thursday in central Tehran to mark the 31st anniversary of Iran's Islamic revolution, …
So to Washington Post writers a demonstration of "tens of thousands" is "bigger" than a demonstration of "hundreds of thousands". A few are more than many? Yes, WaPo says, but that is of course only so when the few support the right cause.
