Shortly after the defeat of Kurdish forces in Afrin, the spokeswoman of Rojava's ruling party the PYD had already announced that SDF would fight Turkish and allied opposition forces using guerilla tactics.[4][5] The PYD's armed branch the People's Protection Units (YPG) also declared that they would target the families of rebel fighters active in the Afrin region, as well as refugees displaced from other parts of Syria in Afrin.[6][7] Following these events the "Wrath of Olives" operation room was established in early summer, 2018, however YPG has denied affiliation with the group.[8]
