French intelligence faults the U.S.-Russia chemical pact and discloses Syria's effort to acquire ingredients for a nerve agent.
France on Wednesday released new evidence directly linking the Syrian regime to an April 4 chemical weapons attack that killed more than 80 people, including many children, and prompted President Donald Trump to order Tomahawk missile strikes against a Syrian air base.
The new evidence, contained in a six-page National Evaluation prepared by French intelligence, represents the most detailed public account of Syria’s alleged use of the deadly nerve agent sarin in the attack on the town of Khan Sheikhoun.
The French report casts fresh doubts on the efficacy of what at the time was billed as a landmark U.S.-Russian chemical weapons pact, which was signed by U.S. Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov in late 2013. The pact was touted as practically eliminating Syria’s “declared” chemical weapons program. France also said that since 2014, Syria has sought to acquire dozens of tons of isopropanol, a key ingredient of sarin, even though it committed to destroying its chemical arsenal in October 2013.
“France assesses that major doubts remain as to the accuracy, exhaustiveness and sincerity of the decommissioning of Syria’s chemical weapons arsenal,” the paper stated. “In particular, France assesses that Syria has maintained a capacity to produce or stock sarin, despite its commitment to destroy all stocks and capacities.”
The French findings, which are based on environmental samples collected in Khan Sheikhoun and blood samples taken from a victim on the day of the attack, bolster claims by the United States, Britain, Turkey, and the Organization for the Prohibition of Chemical Weapons that sarin had been used at Khan Sheikhoun.
But the French account goes further, claiming that the strain of sarin used in the attack on Khan Sheikhoun was identical to sarin samples collected in a previous Syrian government attack on the town of Saraqib on April 29, 2013. Following that attack, France obtained an intact, unexploded grenade containing 100 milliliters of sarin.
The chemical explosive, which was dropped by a helicopter, “was used with certainty by the Syrian regime during the Saraqib attack,” according to the French paper, which was made public in Paris on Wednesday by French Foreign Minister Jean-Marc Ayrault.
An examination of the grenade showed traces of the chemical hexamine, a key signature of the Syrian chemical weapons program. The Syrian Scientific Studies and Research Center, the regime’s chemical weapons incubator, developed a process to add hexamine to the two key ingredients of sarin, isopropanol and methylphosphonyl difluoride, to stabilize it and improve its effectiveness, according to the French account.
“The sarin present in the munitions used on 4 April was produced using the same manufacturing process as that used during the sarin attack perpetrated by the Syrian regime in Saraqib,” according to the French paper. “Moreover the presence of hexamine indicates that this manufacturing process is that developed by the Scientific Studies and Research Centre for the Syrian Regime.”
“This is the first open confirmation from a national government that hexamine is used by the Syrian government in the manufacture of sarin, confirming a hypothesis that had been circulating for over three years,” said Dan Kaszeta, a London-based chemical weapons expert and former U.S. Army Chemical Corps officer, who said that hexamine has not been found in other countries’ sarin programs.
“The presence of hexamine,” he said, “ties all of these sarin incidents together, and it ties them firmly to the Syrian government.”
“The French intelligence report provides the most robust scientific evidence linking the Syrian government to the sarin attack in Khan Sheikhoun,” said Gregory Koblentz, the director of the biodefense graduate program at at George Mason University.”This scientific evidence is a direct refutation of the misinformation being peddled by Russia and Syria.”
The Syrian research center, or SSRC, was established in the early 1970s to secretly develop chemical weapons and other unconventional weapons. As far back as the mid-1980s, the CIA claimed that the Syrian regime was capable of producing nearly eight tons of sarin per month.
The Trump administration, which has disclosed little evidence to back claims that Syria was behind the Khan Sheikhoun attack, this week sanctioned 271 employees of the SSRC in retaliation for the attack.
The Syrian regime has denied that it has ever used sarin, or any other chemical weapons. Syria’s chief backer, Russia, claims that the release of chemical agents in Khan Sheikhoun was the result of a Syrian airstrike against an opposition warehouse containing chemical weapons.
But the French paper challenges that account, saying the “theory of an attack by the armed groups using a neurotoxic agent on 4 April is not credible. … None of these groups has the capability to employ a neurotoxic agent, or the air capacities required.”
