Things are really heating up in the streets of Tehran. The crowds were in the hundreds according to our observers about a couple of hours ago. Now they say between 2,000 or 3,000 people, and we can confirm at least five clashes between security forces and protesters. This is happening in revolution square...very close to Tehran University. This is a protest to commemorate the 10-year anniversary of another protest ten years ago, a crack down that killed several students... The government had said don't come out or there will be a crackdown and that's exactly what's happening. ... [A]t least five clashes we can confirm between security forces and protesters.
