The Iranian blogger Mojtaba Samienejad says that this video, uploaded to YouTube Thursday, shows opposition protesters at Behesht-e-Zahra cemetery in Tehran:

The video shows a car with a video crew on top of it driving up as the crowd chants “Ya Hussein! Mir Hussein!” That suggests that this may have been shot during the reported arrival at the mourning ceremony by the opposition leader Mir Hussein Moussavi. This chant, which has been used throughout the opposition protests, makes reference to the Shiite martyr Hussein and Mr. Moussavi, who shares his name.

As with many of the videos we have pointed to during the post-election protests in Iran, it is difficult to verify the authenticity of this video, due to reporting restrictions imposed by the Iranian government, but Mr. Samienejad is a well-known blogger who has provided reliable information in the past. If readers familiar with Tehran can tell us if this video does seem to have been shot in Behesht-e-Zahra, we would appreciate it.
