As civilian casualties increased, assassinations and bombings also increasingly adopted an ethno-nationalist framing.[16][18] In statements accompanying various attacks, some insurgent groups and pro-Kurdish media outlets described the targets as "settlers", "thieves" and "mercenaries" terms they used to describe Syrian Arab and Palestinian[19]internally displaced persons (IDPs) and refugees, as well as pro-Turkish fighters and their families[20] who had been resettled in the formerly Kurdish-majority region of Afrin,[16][18] which political scientist and cultural anthropologist T. Schmidinger also described as "Rojava's heartland" and "much more Kurdish than any other part of Rojava" prior to the occupation.[21] The settled groups were portrayed by the insurgents as part of an alleged demographic-engineering policy (Turkification) by the Turkish-backed administration,[16][22] a policy that has been documented by independent watchdogs such as the Syrian Observatory for Human Rights (SOHR),[23] while The Guardian had reported in June 2018 that the population balance in the city of Afrin had already been changed from predominantly Kurdish to majority Arab.[24] Schmidinger argues that these and other reported abuses against Afrin’s residents, including forced disappearances, killings, and widespread looting, have intensified Kurdish grievances and, in turn, strengthened the desire for retribution, ultimately helping to fuel the insurgency.[21]
The SOHR stated in an April 2024 report that, since the beginning of Afrin’s occupation and the subsequent insurgency, “attacks and explosions [have] occur[red] almost daily,” although the perpetrator behind many of these incidents was often unclear until a group claimed responsibility.[25][26] In the later stages of the conflict, some attacks were also attributed to infighting between Turkish-backed factions, activity by the Islamic State (ISIS), and other actors.[26][27][28][29]
Shortly after the defeat of the SDF's People's Protection Units (YPG) in the Afrin Region, the spokeswoman for the Kurdish Democratic Union Party (Syria) (PYD), had already announced that the SDF would fight Turkish and allied opposition forces using guerrilla tactics.[32][33] The YPG also stated "We reiterate that these terrorists and their families are the main targets of our forces. Our forces will target all the elements in the Afrin Canton that are in contact or cooperation with the Turkish invasion state."[34][35]
2018
By May 2018, a full-scale insurgency had broken out in the Afrin District, as the YPG[36] along with allied militants and a insurgent group called the Afrin Falcons,[37] began carrying out bombings, ambushes and assassinations against the Turkish Army, SNA forces, and civilians sympathetic or affiliated with them.[36][38]
By mid-2018, the insurgency was mostly focused on the rural areas and Afrin city's outskirts.[36][38] The SOHR reported an escalation in insurgent activity involving landmines, IED detonations, and rocket attacks. According to the organisation, these attacks killed dozens of fighters from various factions as well as members of the Turkish armed forces, with the pace of incidents increasing at an alarming rate.[39] In response the Turkish Air Force regularly targeted guerilla holdouts in the Afrin region, while the Turkish Army and allied militants conducted "sweeping operations" to uncover sleeper cell hideouts between May and July.[36][39]
Pro-SDF guerrilla activity spread to include the Euphrates Shield region, in particular Azaz and al-Bab.[15]

Following his death, the YPG stated that "anyone in cooperation with the invasion forces is our target," including the re-settled Arabs who were, according to the YPG "part of a project by Zaghoul in which they were recruited as mercenaries."[43][44] Additionally the attack killed three fighters of the Sham Legion, Zaghoul's wife, and fully destroyed their vehicle.[44]

The YPG had denied affiliation with the group.[46]
T. Schmidinger told Al-Monitor that the label Wrath of Olives has been interpreted as a reference to claims that Turkey appropriated Afrin’s formerly lucrative olive harvest. During Afrin's occupation Turkish-aligned groups destroyed large numbers of olive trees, pressured farmers to sell their produce at very low prices, and removed or confiscated local olive-oil presses.[21]
