The White Helmets have a hostile relationship with the majority-Kurdish Syrian Democratic Forces (SDF). The group operated in Afrin until the local Kurdish administration banned it in December 2015. It returned following the capture of the city by the Turkish Army and Syrian rebels in the Turkish-led Operation Olive Branch in 2018. In June 2019, after fires set to crop fields by the Islamic State of Iraq and the Levant threatened the food supply of Syrians living in SDF-controlled areas, the White Helmets offered to enter SDF territory and help fight the fires, but permission was denied. Nicholas A. Heras, a Fellow at the Center for a New American Security, stated that the White Helmets, as an organization, referred to Turkey’s operation in Afrin as the "liberation" of Afrin, and maintained that there was "credible evidence" that the White Helmets assisted Turkish soldiers and rebels by providing de-mining assistance. The White Helmets denied that they supported the campaign.
