U.S. airstrikes have hit 20 universities and dormitories across Iran, according to Iranian state media. Videos posted March 28 and 29 showed the aftermath of an attack on the Iran University of Science and Technology in Tehran, where an entire building was reduced to rubble. A few days before, Dr. Saeed Shamghadri, a professor at the university, and two of his children were killed in a strike on their home in northern Tehran.

A strike on a research institute at Isfahan University of Technology damaged several buildings and injured four staff members, according to Iranian state media. Other universities hit include the Faculty of Pharmacy at Shiraz University and two campuses at Urmia University in northeastern Iran, according to United Students, a group run by student activists.

Iran has vowed to retaliate against U.S. university campuses in the region. NYU has closed its Abu Dhabi campus after Iranian leaders declared outposts of U.S. universities as “legitimate targets.”
