Plainclothes police and security forces, many of them armed, have tried to flood Iran’s remaining open universities in an attempt to crush a fourth day of student protests against the supreme leader, Ali Khamenei.
Running battles were reported on some campuses, with videos showing fistfights between the Basji state-backed militia and students at the University of Science and Technology in Tehran. Pick-up trucks with machine-guns were photographed parked outside the University of Tehran, with demonstrations also in Mashhad.
