Syria opens investigation into alleged YPG/SDF mass killing in al-Hasakah

Syria’s Interior Ministry announced early Monday that it has initiated an investigation into reports of a mass killing attributed to the YPG-led Syrian Democratic Forces (SDF) in the northeastern province of al-Hasakah. The ministry stated it is conducting “necessary inquiries” to verify the allegations, which have circulated widely on social media, adding that it is treating the reports with “concern and seriousness.”

Context of Recent Ceasefire and Integration Agreement

The probe comes just one day after Syrian President Ahmad al-Sharaa announced a comprehensive Ceasefire and Full Integration Agreement between the government and the SDF, aimed at restoring state authority in northeast Syria. The alleged incident in al-Hasakah threatens to undermine the fragile agreement, which outlines steps for the SDF’s incorporation into state institutions and the reassertion of Damascus’s control over the region.

Ongoing Tensions and Accusations

The SDF, which is dominated by the Kurdish YPG—considered by Damascus and Ankara as an offshoot of the banned PKK—has been a key actor in controlling parts of northeastern Syria. The Syrian government has repeatedly accused the group of committing human rights violations and obstructing national reconciliation. This investigation signals Damascus’s intent to hold the SDF accountable under state law, even as both sides navigate the newly announced integration process.

Implications for Stability and Reconciliation

If confirmed, the alleged mass killing could escalate local tensions and complicate the implementation of the integration agreement. It also risks drawing renewed international attention to human rights abuses in Syria’s contested northeast. The investigation reflects the challenges facing the Syrian government as it seeks to reestablish sovereignty in areas long held by non-state armed groups while addressing longstanding grievances and security concerns.
