TRAC’s London Analyst, Sophia Badawy has been monitoring escalating tensions between Hayy’at Tahrir al-Sham (HTS) and Tanzim Huras al-Din over the past week. After the formation of Tanzim Huras al-Din led Stand Firm Operations Room, Hayy’at Tahrir al-Sham (HTS) has started a series of arrests on its former commanders who became part of Tanzim Huras al-Din’s Stand Firm Operations Room. Now, there is growing speculation that Tanzim Huras al-Din has already managed to take control of HTS’ Central Prison, Al-Kansarwah factory, and that the group is preparing to storm the administrative capital of HTS in Idlib, Syria. If found to be true, Abu Mohammad al-Joulani’s was right to fear that Tanzim Huras al-Din was a threat to his seat of HTS power.
