A Dutch court has sentenced a former interrogator for the Assad regime to 26 years imprisonment after convicting him of torture and ill-treatment of eight detainees held at three detention facilities around Salamiyah, in central Syria, according to a ruling published by the Rechtbank Den Haag.

The case was adjudicated under the principle of universal jurisdiction — the legal doctrine that permits national courts to prosecute individuals for certain grave international crimes regardless of where those crimes occurred or the nationality of the perpetrators or victims. The Netherlands has developed one of Europe's more active dockets for such cases. The Hague's international crimes chamber previously convicted Mustafa A. on 27 August 2025 for co-perpetrating a crime against humanity, and a separate appellate ruling resulted in a twelve-year sentence for torture and the war crime of torture — cases that, taken together, reflect the court's sustained engagement with the Syrian dossier.

The Salamiyah detention centers at the center of this latest conviction were part of the security apparatus that Syrian intelligence services operated across the country during the civil war. Salamiyah, a town in Hama Governorate with a predominantly Ismaili population, sits in a region where regime forces maintained a dense administrative and security presence. Detainees held in facilities of this kind routinely faced incommunicado detention, denial of legal counsel, and systematic physical abuse — conditions documented extensively by the UN Commission of Inquiry on Syria and by organizations including the Syrian Archive and Physicians for Human Rights.

The 26-year sentence is among the heavier penalties handed down in any European universal-jurisdiction proceeding involving Syria. For comparison, the landmark 2022 Koblenz trial — in which a former Syrian secret police officer, Anwar Raslan, was convicted of crimes against humanity — resulted in a life sentence under German law. Sentencing ranges across European jurisdictions vary considerably, reflecting differences in national penal codes rather than divergent assessments of culpability, which complicates victim advocates' attempts to frame outcomes as equivalent.

The broader context matters for practitioners tracking accountability mechanisms. The International Criminal Court cannot reach Syria directly: Damascus is not a party to the Rome Statute, and Russia's Security Council veto has blocked referral twice. That structural gap has pushed accountability efforts toward universal-jurisdiction proceedings in Europe — Germany, Sweden, France, and the Netherlands have all brought Syrian cases to trial. Each conviction adds to a body of evidentiary record that prosecutors, future tribunals, and any eventual transitional justice process in Syria could draw on. The Assad regime collapsed in December 2024; what institutional architecture emerges in Damascus, and whether it will engage with accountability demands from survivor communities and diaspora groups, is still unresolved.

Universal-jurisdiction cases carry specific evidentiary challenges that make convictions of this kind genuinely difficult to obtain. Prosecutors must establish the defendant's presence in a specific facility, their command or direct role in specific acts, and the legal threshold for torture under international humanitarian law — all from documentary evidence and witness testimony gathered years after the fact, often from survivors now scattered across multiple countries. A conviction on eight counts of torture and ill-treatment, with a sentence of this length, indicates a substantial evidentiary record was assembled and accepted by the court.

For the Syrian survivor and diaspora communities that have driven referrals to European prosecutors — often providing testimony at considerable personal risk — the ruling is a concrete procedural outcome in a process that has moved slowly and unevenly. The verdict does not close the broader accountability gap, but it extends the evidentiary and legal record that any future Syria tribunal would inherit.
