Videos showing harrowing scenes of bleeding protesters, burning roadblocks and snipers on rooftops have emerged after Iran lifted a near-total internet blackout, opening a window onto what analysts say was one of Tehran's bloodiest crackdowns.
This repression "was harsher" than during previous protests in Iran, Kamran Matin, senior lecturer in International Relations at Sussex University in Britain, told AFP in Nicosia.
"All the videos I have seen from before the internet was shut down show that from the moment of the gathering of people to 'shoot to kill' was very short."
"You're just seeing what's in front of the camera, so it's really hard to put it in numbers. How many people are there, how they were instigated... what if they are older videos. There are so many what-ifs."
