On Monday, the Kurdish-led SDF announced that they are considering sending reinforcements to Afrin amid the Turkish operation there.

Erdogan said that Turkish troops and allied Syrian fighters have killed at least 268 Syrian Kurdish fighters since the operation against the Afrin enclave was launched on January 20. That's what the unraveling US relationship with "NATO partner" Turkey has come to: military brinkmanship... "If the United States doesn't stop this, we will stop it", Cavusoglu was reported as saying on Tuesday.
