NRO has this piece written by an Iranian student:
Each night we set to the streets only to be swept away the next dawn by agents of the regime. Two nights ago, on Amirabad Street, we wrote “Down with Khomeini” on the ground. Before long, the mullah’s vigilantes attacked us on their motorcycles. They struck a female student before my eyes so harshly that she was no longer able to walk. As she fell to the ground, four members of Ansaar-e-Hezbollah surrounded her, kicking her. When I and two other students threw stones at them so that they would leave her alone, they threatened us. We escaped into a lane and hid in a house whose owner, an old lady, had left the door open for us. A few minutes later, we saw the young lady being carried away by riot police, her feet dragging on the ground, her shattered teeth hanging out of her still-bleeding mouth.
Read, as they say, the whole thing.
