Syrian officials have taken 18 people into custody who are believed to have played key roles in the Assad government’s chemical weapons operations, as newly uncovered evidence may strengthen international war crimes prosecutions.
The arrests come alongside the discovery of chemical weapons materials and munitions that could help investigators build cases against those who oversaw the deadly program during Syria’s civil war.
Retired Brig. Gen. Mustafa al-Sheikh, a military affairs expert, explained to The Media Line that finding munitions matching those from the Ghouta and Al-Latamenah attacks represents a major breakthrough for international investigators. “Any technical match between the newly discovered materials and previously documented evidence could provide additional grounds for legal accountability and strengthen efforts to prosecute those responsible for the use of chemical weapons,” he stated.
A United Nations investigation from September 2013 found “clear and convincing evidence” that Sarin gas was used in the Ghouta area near Damascus, an assault that reportedly caused hundreds of deaths.
Former Secretary-General Ban Ki-moon called the investigation results “deeply disturbing.” The UN team concluded that “chemical weapons have been used in the ongoing conflict between the parties in [Syria], also against civilians, including children, on a relatively large scale.”
The UN investigation revealed that 85% of blood samples collected from Ghouta locations showed positive results for Sarin, while most rocket debris also contained traces of the lethal nerve agent.
“This is a war crime,” Ki-moon declared to the UN Security Council in 2013 following the report’s release. “The international community has a responsibility to hold the perpetrators accountable and to ensure that chemical weapons never re-emerge as an instrument of warfare.”
French courts have issued international arrest warrants for Bashar Assad regarding the 2013 Ghouta chemical attacks, determining that such crimes are not covered by head-of-state immunity. Additional legal actions in Germany and Sweden use universal jurisdiction principles, while the International Criminal Court cannot automatically intervene since Syria has not signed the Rome Statute.
Mohamed Katoub, Syria’s permanent representative to the Organization for the Prohibition of Chemical Weapons (OPCW) in The Hague, revealed that officials detained 18 people suspected of running and operating the previous government’s chemical weapons operations. Katoub stated that those in custody include high-ranking military, political, and technical personnel, though their names and exact positions remain undisclosed.
These detentions mark the start of what may become an extended legal and security investigation, especially as international demands persist for accountability regarding banned weapons used against civilians throughout the conflict.
Syrian officials announced a major step forward in dismantling the chemical weapons infrastructure created under former President Bashar Assad, following reports from the OPCW and Syrian authorities about discovering munitions, chemical substances, and specialized equipment connected to the program. The discoveries also included documentation that may help explain the extent of activities that stayed hidden despite years of international oversight and disarmament work.
A source within Syria’s Ministry of Defense informed The Media Line that specialized government units found raw materials, munitions, and missiles linked to the chemical weapons program used during the Syrian conflict, including weapons similar to those used in poison gas attacks throughout the war.
Search operations resulted in recovering more than 70 missiles and bombs designed for the former government’s chemical weapons program, though the OPCW indicated the materials are still being analyzed technically, according to the anonymous source.
The OPCW verified that recent inspection missions discovered dozens of munitions, chemical materials, and associated equipment across multiple Syrian locations, along with thousands of documents connected to the former government’s chemical weapons program. OPCW experts are currently conducting technical analysis of the materials.
This discovery occurs as Syria’s new leadership attempts to resolve one of the war’s most sensitive and complicated issues, while facing continued international pressure to fully reveal the status of undeclared chemical weapons supplies and ensure accountability for their use.
In the first comprehensive official statement about the findings, Syrian Foreign Minister Asaad al-Shaibani said national teams successfully located “munitions, precursor materials, as well as mixing and storage equipment,” noting that the materials were secured and moved to specialized facilities for destruction. He described the accomplishment as resulting from “months of national, intelligence, and technical work,” including gathering and analyzing information, accessing dangerous sites, and enabling OPCW inspection visits to dozens of locations connected to the former program.
Al-Shaibani also mentioned that Syrian authorities made progress in pursuing people involved in the former government’s chemical weapons program, describing these efforts as demonstrating cooperation between Damascus and the OPCW within what he termed a “new Syria” founded on transparency and international collaboration.
Syria’s mission to the OPCW reported that search operations identified sites connected to the former chemical weapons program and found munitions and materials linked to previous chemical attacks during the war. The mission stated that investigators discovered 54 aerial bombs similar to those used in the 2017 Al-Latamenah attacks and 25 ground-to-ground munitions resembling those used in the 2013 Eastern Ghouta attack, plus sarin precursor materials and equipment for mixing and storage.
Emphasizing growing international attention to the matter, US Special Envoy for Syria Thomas Barrack called the discoveries “an important milestone” in building a new Syria and strengthening international security. Barrack said uncovering remnants of the chemical weapons program represented another step toward ending what he termed the “brutal legacy” of chemical weapons in Syria. He attributed the progress to cooperation between Syrian authorities and the OPCW, with support from the United States and international partners.
“A safer, more sovereign, and more accountable Syria is in the interest of the Syrian people and the world as a whole,” Barrack stated.
The chemical weapons matter remains among the most controversial and sensitive elements of the Syrian conflict, connected to multiple attacks that prompted widespread international criticism and became central to efforts holding the former government accountable. While Syria agreed in 2013 to eliminate its chemical weapons arsenal under international supervision, the OPCW has continued finding gaps, inconsistencies, and unresolved questions about Syria’s declarations.
Observers think the recent discoveries, combined with unprecedented cooperation between Syrian authorities and international organizations, may mark a crucial moment in international accountability efforts, especially if ongoing investigations confirm previously undeclared stockpiles, equipment, or operational networks outside earlier disarmament agreements. Such findings could begin a new phase in legal investigations into one of the Syrian war’s most disputed legacies.
