The prisoner agreement demonstrated that when Lebanon and Syria choose to act through legal channels, they can reach agreements on sensitive cases, even those entangled in decades of mutual grievance. But it also created a stark contrast with how the Lebanese government is handling the parallel question of former regime figures in the country, where it has no declared policy, no legal framework, and no unified institutional response. It is imperative that the Lebanese government address the situation, but what remains unclear is whether it can do so on its own terms, through a coherent legal and institutional framework, before the terms are dictated by forces beyond its control.
The situation is worse than mere neglect. Lebanon has received formal legal requests from France, Germany, and the United States demanding action on individuals convicted of or charged with crimes against humanity. It has not responded to any of them. Its own institutions, security agencies, the judiciary, the executive, are each handling fragments of the case without coordination, producing parallel actions that amount to nothing. Meanwhile, local and international media outlets have documented active insurgency networks operating in part from Lebanese territory, with former regime commanders distributing payments, recruiting fighters, and coordinating with exiled generals in Moscow.
This policy brief recommends that Lebanon pursue a dual-track approach. On the domestic track, the government should respond formally to the outstanding legal requests, establish a legal framework that assigns institutional responsibility for classifying and managing these individuals, and shift decision-making from agency-level improvisation to declared government policy. On the diplomatic track, it should pursue bilateral cooperation with Damascus, building on the prisoner repatriation model, and explore managed departures to third countries for specific cases, a mechanism Lebanon has used before. These tracks should operate simultaneously and be linked to other sovereign files with Syria, above all the prisoner dossier, within a comprehensive bilateral framework rather than as isolated crisis responses.
The Information Fog
In the days following the fall of the Assad regime in December 2024, the Lebanese newspaper Nida al-Watan reported that the number of Syrian security and intelligence officers who had fled to Lebanon were estimated to be “in the thousands,” and that Hezbollah and a Lebanese General Security officer at the Masnaa border crossing had coordinated the arrival of prominent Assad regime figures. Among them was Ali Mamlouk, Assad’s national security adviser, who was, according to the report, hiding in Beirut’s southern suburbs under Hezbollah protection.
Days later, Saudi channel Al-Hadath reported that Mamlouk flew from Rafik Hariri International Airport and arrived in northern Iraq, with the AFP newswire subsequently documenting he had left Iraq for Russia. Lebanon’s Interior Minister, however, denied that Mamlouk had entered the country through a legal border crossing.
Adding to the information fog the Lebanese government has let settle over the issue are the ostensibly credible but conflicting media investigations that have arisen. In December 2025, the Wall Street Journal reported that Syrian and Western officials suspected Jamil Hassan, the former head of Syria’s Air Force Intelligence and arguably the single most wanted figure from the Assad security apparatus, was in Lebanon, where networks linked to the former regime’s intelligence apparatus were reportedly regrouping. Lebanese judicial authorities told the paper they had “no confirmed information” about his whereabouts. Ten days later, a New York Times report placed him in Moscow, citing three people who said they had met him there.
Thus, while the details surrounding Syrian regime figures in Lebanon remains hazy, the general picture that has emerged suggests two categories. The first consists of senior figures who used Lebanon as a transit point before moving on, though whether some have returned or maintained operational links through Lebanese intermediaries remains unclear. The New York Times, for instance, reported that Kamal al-Hassan, the former military intelligence chief now in Moscow, has traveled to meet collaborators in Lebanon, Iraq, and Syria over the past year.
The second category is more troubling from the standpoint of sovereignty: mid-level and field commanders who appear to have settled in northern Lebanon, particularly in Alawite communities in Akkar and the Jabal Mohsen area, following the sectarian violence targeting Syrian Alawites along that country’s coast in March 2025. Their embedding in local communities complicates any response, since removal would require navigating local political dynamics alongside the legal and diplomatic ones.
The Legal and Institutional Vacuum
Former Syrian regime figures in Lebanon are not refugees, and they are not ordinary administrative cases. They do not fit any of the legal categories Lebanon typically uses to handle foreign nationals on its territory. But they are still protected by international law, which means they cannot simply be expelled, detained, or handed over without legal process.
What makes this situation additionally fraught for Lebanon is that three competing considerations are pulling in different directions at once. Lebanon has the sovereign right to decide who stays on its territory. It also has international legal obligations, above all the principle of non-refoulement, which prohibits sending people to places where they may face torture or persecution, and the guarantee of a fair trial. And it faces political and security pressures tied to its relationships with Damascus, the broader region, and beyond. Any action, or inaction, on Syrian regime figures implicates all three considerations.
Making this predicament concrete rather than theoretical is the accumulation of formal legal demands that Lebanon has received but has not responded to. In November 2025, France submitted a formal legal request to Chief Public Prosecutor Judge Jamal Hajjar, demanding assistance in tracking and arresting three former senior intelligence officials: Jamil al-Hassan, Ali Mamlouk, and Abdelsalam Mahmoud, former head of the investigation branch in Air Force Intelligence. The request was part of an ongoing case in which all three had been convicted in absentia by the Paris Cour d’assises in May 2024 for complicity in crimes against humanity, specifically the torture and killing of French citizens of Syrian descent held in Air Force Intelligence detention. The French filing included Lebanese telephone numbers said to be in regular contact with the suspects, a detail that implied France believed the men were reachable through Lebanese networks even if their physical location was uncertain.
Lebanon had also previously received an Interpol notice demanding implementation of a US arrest warrant for al-Hassan and Mamlouk. The day after the fall of the Assad regime, US authorities unsealed separate war crimes charges against al-Hassan and Mahmoud. Germany had issued an arrest warrant for al-Hassan in June 2018 for crimes against humanity, and the US State Department publicly called on Lebanon to facilitate his extradition to Berlin at that time, when he was reportedly receiving medical treatment in a Lebanese hospital. Lebanon did not act on the German warrant then, and al-Hassan’s subsequent movements remain disputed.
These official requests carry legal obligations. France, Germany, and the United States have each pursued formal judicial instruments through recognized channels. Yet no arrests have been made, no formal refusals have been issued, and no public legal reasoning has been offered for the inaction. The silence is itself a form of policy, though one that Lebanon cannot defend before any external interlocutor as a principled legal position.
