In late July 2015, the third phase of the Kurdish–Turkish conflict between various Kurdish insurgent groups and the Turkish government erupted, following a failed two and a half year-long peace process aimed at resolving the long-running conflict. Since 2016, the Turkish military and Syrian National Army have conducted operations against the Syrian Democratic Forces, leading to the Turkish occupation of northern Syria. In May 2022, the conflict gained global geopolitical significance as Turkey opposed the accession of Finland and Sweden into NATO, accusing them of supporting the PKK.
