New Syrian Chemical Weapons Find Could Help Prosecute Perpetrators of War Crimes

Syrian Authorities have detained 18 individuals suspected of involvement in operating and managing the Assad regime’s chemical weapons program

The recent discovery of Assad-era chemical weapons munitions and materials in Syria has implications beyond the identification and destruction of hazardous stockpiles. The evidence could help investigators trace the military and security command structures that oversaw the chemical weapons program under Assad and support efforts to hold those responsible for war crimes committed during the civil war accountable.

Retired Brig. Gen. Mustafa al-Sheikh, a military affairs expert, told The Media Line that the discovery of munitions similar to those used in the Ghouta and Al-Latamenah attacks could mark an important development in international investigations. “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 said.

A September 2013 United Nations investigation into chemical weapons use in Syria concluded that there was “clear and convincing evidence” that Sarin gas was deployed in the Ghouta area outside Damascus, an attack that reports said killed hundreds of people.

Then-Secretary-General Ban Ki-moon described the findings as “deeply disturbing.” The investigative team determined 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.”

According to the UN probe, 85% of blood samples from the sites in Ghouta tested positive for Sarin, and the majority of the rocket fragments were also found to be carrying the deadly nerve agent.

“This is a war crime,” Ki-moon said to the UN Security Council in 2013 after the report was published. “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 an international arrest warrant for Bashar Assad over the 2013 Ghouta chemical attacks, ruling such crimes are not protected by head-of-state immunity. Separate efforts in Germany and Sweden rely on universal jurisdiction, while the International Criminal Court lacks automatic jurisdiction because Syria is not a Rome Statute members.
