Talal Silo, a former spokesperson of the SDF in Syria who recently defected and came to Turkey says the United States gave the approval to evacuate of Daesh militants in three different cases in Syria, including the evacuation of Raqqa.
The SDF was formed and backed by the US to drive Daesh out of northern Syria. However, the group has strived for permanent presence in the region. With Daesh virtually erased from Syria, the SDF militia looks instead towards regional autonomy.
