Footage of Rafsanjani's speech - calling for the release of prisoners

This video was taken during Rafsanjani's speech today. According to an Iranian colleague, in this clip, "Rafsanjani is talking about releasing the prisoners who were arrested during the recent protests. Some people then approve of his words by shouting "God is great!" and "political prisoner must be released!" slogans. Some others ask them to be quiet so they can hear the rest of Rafsanjani's speech."
