During the 1980s, Tadmor prison housed thousands of Syrian prisoners, both political and criminal and it was also the scene of the June 27, 1980 "Tadmor Prison massacre" of prisoners by Rifaat al-Assad, the day after the Syrian branch of the Islamist Muslim Brotherhood narrowly failed in an attempt to assassinate his brother, president Hafez al-Assad. Members of units of the Defence Brigades, under the command of Rifaat al-Assad, entered Tadmor Prison at dawn and murdered an estimated thousand prisoners in the cells and the dormitories. The massacre is well known throughout Syria.
