“Caesar” photos document systematic torture

Syrian Military Police defector “Caesar” Passes Key Evidence to German Federal Prosecutor

Syria – Torture – Caesar

Thousands of photos of corpses in Syrian government detention facilities, in high definition, many containing metadata – they are key evidence for the ongoing investigations into human rights abuses under Syrian President Bashar al-Assad.

In June 2018, the German Federal Court of Justice (Bundesgerichtshof) issued an international warrant against Jamil Hassan on the basis of the so-called Caesar Files, their metadata as well as witness statements by Syrian torture survivors. Hassan was the head of the Syrian Air Force Intelligence Service until July 2019 and therefore responsible for torture in thousands of cases.


In September 2017, the group around the former Syrian military police employee “Caesar” took for the first legal action by filing together with ECCHR a criminal complaint with the German Federal Prosecutor in Karlsruhe against Jamil Hassan and other senior officials from the Syrian intelligence services and the military police concerning crimes against humanity and war crimes.

A representative of the Caesar Files Group provided the federal prosecutor with a set of high-resolution images and metadata. The metadata can be used to verify the photographs and provide further information about them. This adds to the evidentiary value of the images and paves the way for further investigatory steps. As one of the few countries where the principle of universal jurisdiction applies, Germany is playing a key role in the fight against impunity in Syria.


The photos filed were taken in Syria between May 2011 and August 2013. They were subsequently obtained by the Caesar Files Group and smuggled out of the country. The images show the bodies of people who were tortured and died in Syrian government detention facilities.

The metadata and the accompanying criminal complaint from ECCHR and the Caesar Files Group provide information on the locations and institutions involved as well as the torture methods used and the causes of death. Apart from Jamil Hassan, the complaint is directed against the heads of the Syria’s National Security Bureau, the Military Intelligence Service, the General Intelligence Directorate and the Military Police.



Q&A: Legal background of the criminal complaints on the Syrian torture cases filed in Germany.

Arrest warrants against those responsible for systematic repression and torture under Assad would be an important signal for survivors, relatives of those affected, and those still detained in the prisons of the Assad regime.

The fact that the German Federal Prosecutor opened investigations focusing on Jamil Hassan as a specific Syrian officials concerning international crimes in Syria, and the Federal Court of Justice (Bundesgerichtshof) issued an international arrest warrant, is a milestone and represents an important step towards ending impunity for torture in Syria.

Like Jamil Hassan, most of the high-ranking officials responsible for torture and other human rights violations in Syria still live in the country. But if they are subject to an international arrest warrant and were to travel outside Syria, they can be arrested and extradited to Germany. Germany could then file charges and open criminal proceedings.

The case of the Chilean dictator Augusto Pinochet shows that international arrest warrants against high-profile politicians and military figures are possible and effective. In 1998, the Spanish investigative judge Baltasar Garzón issued an international arrest warrant against Pinochet for genocide and other crimes. While Pinochet was visiting London, he was arrested by Scotland Yard and his extradition to Spain was approved by the then Home Secretary Jack Straw. The Chilean government negotiated that he be freed on humanitarian grounds, but Pinochet's arrest in London ultimately triggered a broader process of legal reckoning with the crimes of the dictatorship in Chile.

Currently, there is absolute impunity in Syria, and the Assad regime is neither interested in investigating the cases of torture, nor in bringing the perpetrators and the responsible officials before a court.

Through adoption of the Rome Statute, and establishment of the International Criminal Court (ICC) in 2002, international criminal justice was enabled to prosecute war crimes, crimes against humanity, and genocide before the court in Den Haag. However, this option is currently not available for the crimes committed in Syria. The ICC is not authorized to start an investigation into the crimes, as Syria is not a party to the Rome Statute. At the same time, a referral to the court by the UN Security Council is currently blocked by Russia and China.

However, the Independent International Commission of Inquiry on the Syrian Arab Republic (UN CoI Syria) was established in August 2011 by the Human Rights Council through resolution S-17/1 adopted at its 17th special session with a mandate to investigate all alleged violations of international human rights law since March 2011 in the Syrian Arab Republic.

On one hand, UN CoI Syria’s investigators have been gathering evidence against all parties to the conflict for more than six years. They also work in the neighboring countries of Lebanon, Jordan, Iraq and Turkey. On the other hand, recently established International, Impartial and Independent Mechanism to Assist in the Investigation and Prosecution of those Responsible for the Most Serious Crimes under International Law Committed in the Syrian Arab Republic since March 2011 (IIIM) is tasked with collecting, preserving, and consolidating evidence, while also preparing strong evidentiary files that can be used by prosecutors for independent criminal proceedings. The information gathered by the corroboration of the UN-Commission and the UN-Mechanism is therefore essential for future legal proceedings in national, regional, or international courts. The principle of universal jurisdiction enables domestic courts to initiate judicial proceedings and to hold perpetrators of all ranks accountable. In Germany and other European Union (EU) Member States, investigations have been brought in this regard.

Serious crimes concern international society as a whole, and must be responded to. For this reason, it is a duty of the national jurisdictions of third party states, like Germany, to investigate the serious crimes committed in Syria and to prosecute the responsible officials.

The German Code against International Crimes (CCAIL), which entered into force in 2002, enables German courts to prosecute international crimes committed in Syria. By adopting the CCAIL, Germany adapted its national criminal law to the standards set by International Criminal Law, and in particular by the Rome Statute of the ICC.

The CCAIL affirms the principle of universal jurisdiction, which constitutes the legal basis for prosecution of genocide, crimes against humanity, and war crimes by German courts. According to the CCAIL, the Federal Public Prosecutor can investigate international crimes, even if they were committed outside of Germany. This means that jurisdiction of the courts is independent from the location of the crime as well as from its victim or perpetrator.

Since 2011, the Federal Public Prosecutor has been conducting several person-related investigations as well as a general investigation (Strukturverfahren), which addresses the overall situation in the country and goes beyond individual cases.

A criminal complaint presents an avenue in the German legal system to report an assessment of facts in form of a crime or multiple crimes. It is the task of the investigative authorities to determine the suspect responsible.

The criminal complaints submitted by Syrian torture survivors as well as ECCHR, SCM and SCLRS address the policy of systematic torture in prisons of the Syrian Military Intelligence Service. According to the Code of Crimes against International Law (CCAIL), systematic torture is to be qualified as a war crime and a crime against humanity.

For example, the first criminal complaint lists five officials known by name and further unknown officials of the Syrian Military Intelligence Service and the Syrian government as those who bear responsibility for the addressed crimes.

A criminal complaint is often the first step to initiate an investigation by the authorities of a third country. The complaints should make the Public Prosecutor aware of a certain situations or acts which from the perspective of the complainants meet criteria of a criminal offence.

Within the general investigation of the situation in Syria, the Federal Public Prosecutor has already gathered and secured evidence. However, this investigation mostly targeted the perpetrators of lower ranks. The criminal complaints submitted by ECCHR should persuade the Federal Public Prosecutor to target high-level officials of the Syrian Intelligence Service, to investigate their crimes and to issue international arrest warrants against them.

In June 2018, it was finally time: German authorities issued an international arrest warrant for Jamil Hassan, who was head of the Syrian Air Force Intelligence Service until July 2019.

As president and commander-in-chief of the armed forces of the Syrian Arab Republic, Bashar al-Assad is at the top of the military chain of command. He has ultimate command over acts of all security and military institutions, including the four Syrian intelligence services, the Ministry of Defense, and the National Security Bureau. President Assad thus undoubtedly bears responsibility for their crimes.

As a sitting head of state, however, al-Assad is shielded from prosecution before national courts in third countries. In Germany he is protected by the international law concept of immunity ratione personae as set out in Paragraph 20(2) of the Courts Constitution Act (GVG) and Article 25 of the German Basic Law (GG). This means that no criminal proceedings can be undertaken against him at this time. However, as part of its investigations, the German Federal Public Prosecutor is gathering evidence on potential crimes by Assad. This information could be used in the future, for instance when he is no longer president, or if charges are leveled against him by the International Criminal Court or a Special Tribunal.

The primary goal of submitting criminal complaints is to initiate further person-related investigations, which will legally address the described crimes in a dignified way.

The investigations initiated by the Federal Public Prosecutor in 2011 were an important first step. Seven years later, however, it is time to take further steps: the German judiciary should not focus on low-rank perpetrators, but must investigate the acts of those officials who bear the actual responsibility for the crimes. Even though those officials are still in Syria, certain steps can be taken, e.g. by issuing international arrest warrants like the one for Jamil Hassan. To take these steps, the Federal Public Prosecutor and the Courts should be given additional resources by the state. There is a growing need for educated investigators and better protection for witnesses.

The criminal complaints are based on testimonies of women and men, who were imprisoned in different 'branches' (detention facilities) of the Syrian Military Intelligence Service in Damascus, and photographical evidence accompanied with metadata that was provided by the group around the former Syrian military police employee, "Caesar."

In addition to the testimonies of the victims, photographical evidence, and metadata, numerous public documents and reports have also been used as sources for the criminal complaints. Many of the crimes committed in Syria, including the crimes of torture, have been well documented through the years by international and Syrian human rights NGOs.

Testimonies of the survivors and witnesses, official documents, as well as pictures of the victims and sites of crime, considered as a whole, demonstrate that the Syrian regime is guilty of crimes against humanity and war crimes.

In order to achieve accountability for the systematic and widespread human rights violations in Syria further legal interventions have to follow – against the Assad government, against transnational corporations, against third states involved in military intervention in the conflict as well as against organizations such as IS.

Without justice for those affected by the crimes committed in Syria, there is no prospect of a political solution. Justice for human rights crimes are essential for affected individuals. However, accountability has contributed to the prevention of other conflicts and for the development of the rule of law as well as democratic principles after the end of war in Syria.

Further fields of possible legal interventions may be exports of conventional weapons, other armaments or surveillance technologies to the conflict parties, as well as targeted sexual violence against women and the use of chemical weapons in Syria.

Crimes against humanity

Crimes against humanity – defined as a systematic attack on a civilian population – tend to be planned or at least condoned by state authorities: heads of government, senior officials or military leaders. In some cases, companies also play a direct or indirect role in their perpetration.
