Reports have been bubbling up on Twitter of a major government raid on dormitories at Tehran University last night. Photos and video posted online show destroyed doors, ransacked rooms, and students displaying their injuries.

Now the Guardian, a major UK newspaper, has posted an eyewitness report on last night’s events online:

The protests at a university in Tehran were bigger than on Saturday night. Students gathered in front of the dormitory, and they were throwing stones at bricks at the riot police and basijis [militiamen] who had attacked them with teargas.

At 1.30am riot police opened fire with teargas. We could hear the shots every minute. Three protestors were hit – one in the leg, one in his eye, and one in his neck – and then six more were hit, but nobody was allowed to go and help them.

They were screaming and the student who was hit in the eye was in a terrible condition, but the police didn’t let anyone help them. Then the police went into the dormitory complex.

They took over block number 23 and severely attacked the students there with plastic batons. The police set fire to the student’s belongings and their beds. Then special guards from the army entered the dorms carrying rifles.

At least 300 special guards and riot police on motorbikes joined the ones in the dorms, and they were firing more teargas. I was in dorm number 22 when they broke down the doors and entered the building, firing at least 10 teargas rounds.

We had nowhere to hide but the toilets and bathrooms, and they shouted “You traitors to the Islamic republic, you bastards, leave the building or we’ll shoot you all.” Many students were severely wounded in the attack – we could hear injured students groaning and shouting for help.

At 3am the special guards and riot police said on loudspeakers: “If you evacuate the building we won’t harm you. Otherwise you’ll all be injured or killed.”

Then all the students came out of the building in lines, with their hands on their heads. The police hit then with batons and some started to shout that they had conquered the dorms. Eventually they let us go back to our rooms, but at least ten had been shot, some appeared to have been killed, and hundreds were injured.

10 am update: Reuters reports that four hundred Tehran University students have staged a protest at a mosque on campus this morning, announcing plans for a sit-in tomorrow. One says more than a hundred students were arrested in last night’s militia assault on the dorms.

1:45 pm update: Many more photos of destruction of dorm rooms. Lots of broken doors, shattered glass, fire damage.

10 pm update: A report claims five students were killed in the dorm assault. A committee of the Iranian parliament will be conducting an investigation of the incident.
