Iran Embassy in London films protesters...

I hope the protests continue and that they get millions of feet of film...

Hundreds of British protesters have been secretly filmed by staff at London's Iranian Embassy, sparking claims that authorities are trying to spread fear.

Protesters have taken to the streets around the Iranian embassy in London in the wake of claims of widespread rigging during this week's elections.

But several who attended last night's protest have been left fearing reprisals after their actions were secretly filmed by a camera inside the embassy building.

Pictures obtained by The Evening Standard reveal a video camera on the top floor of the embassy in Prince's Gate filming the protesters.

The camera is noticeable from street level and was placed high in an attic window.

Some protesters covered their faces because of fears they or their relatives may be targeted by the Iranian authorities following the protests.

The crowds of up to 400 have been holding anti-government banners and chanting slogans against president Mahmoud Ahmadinejad and wearing the green colours of opposition leader Mirhossein Mousavi.

Mostafa Sanatnama, one of the protest organisers, accused Iranian authorities of trying to 'spread fear'.

He said: 'People think they have to be careful. Most of us still have friends and relatives in Iran. But even if they are filming us it won't scare people away.

'What can they do when there are thousands on the streets?'

Maryam, a 26-year-old student, is due to fly back to Tehran in two weeks and says she was deeply troubled by the covert filming.

She said: 'I'm worried they'll take my passport or won't let me get a flight back.'
