Turkish forces entered the Afrin region along with the Turkish-backed Free Syrian Army, according to the Turkish state-run Anadolu Agency. Syrian President Bashar al-Assad denounced what he called "Turkish brutal aggression on the Syrian city of Afrin," according to the state-run Syrian Arab News Agency (SANA). Earlier in the day rockets fired from Syria also hit the Turkish border city of Kilis, according to Anadolu. Turkish forces have said they are targeting ISIS as well as Kurdish militia in Afrin. A 30,000-strong, US-trained border force from the Syrian Democratic Forces, dominated by YPG fighters, is to be trained in Manbij.
