Hayat Tahrir al Sham (HTS) related media outlets citing some local sources report the plans of the Kurdish security police Asaysh to assassinate all the field commanders of Arab origin in the ranks of the Syrian Democratic Forces (SDF).
In accordance with the given information this will be done in order to stop a severe discord in the ranks of the pro-Kurdish militia and to prevent the Arab tribes from turning to Assad’s “criminal regime” prior to the upcoming Turkish invasion.
It is unknown in whose favor HTS propaganda acts in spreading such rumors, since it works for Bashar Assad anyway, and Turks as well, as Syrian al Qaeda supreme leader Abu Muhammad al Juliani is surely supposed to obey orders from Turkey.
Meanwhile the practice of detentions and repressions for Arab tribes fighting for SDF has some recent examples. In summer of 2018 an Arab tribe that was involved in the battle of Raqqa was severely suppressed by the SDF security force.
