A compound that houses elements of the elite Kurdish Yekineyen Anti-Terror (YAT) unit was bombed by Turkish forces in the early stages of the invasion of Northern Syria.

YAT is a counterterrorism unit created and trained to hunt down Islamic State (ISIS) terrorists. U.S. Special Operations Forces (SOF) are training, advising, and operating with the elite Kurdish outfit as part of Operation Inherent Resolve, the fight against ISIS.

Even before the Turkish invasion, the Pentagon has denied that American Special Operations units have provided training or material support to the YAT. Sources familiar with the region, however, told SOFREP that the Kurdish counterterrorism unit has received training from both Special Forces Operational Detachment Alphas (ODAs) and Delta Force teams.

Referring to the work of the YAT, the YPG press office said that the “YPG provides no free-ground for any terrorists in Northern Syria, including ISIS sleeper-cells which have been heavily targeted by the YPG Counter Terrorism Units since the battle in Baghouz.”
