I am still hearing about the students protesting in Tehran and other major cities.
BBC Persian service ( BBC World - English ) is also reporting that the protests have been going on for the past four nights but no one knew about it in other parts of the city and this is correct as far as I checked with my friends in Tehran, and I was told that they had no idea if there was any uprising or unrest existing any where.
I also heard a caller on Persian service of Voice of America asking people to join the students if they can and another was saying that revolution of 1979 also started in city of Tabriz where there are major protests going on right now.
It seems the protests are still well underway in Tehran & major cities such as Ahwaz, Tabriz, Kermanshah
Shahram, a former law student at Tehran University, reports about the protest as well
