>> There's further evidence that the Syrian government was behind this, the largest chemicals weapons attack since the civil war began seven years ago. For the first time, lab tests linked the government's stockpiles to the sarin gas attack in the Damascus suburb in 2013. Hundreds of civilians died. Western governments have long blamed President Assad, who points the finger at rebel forces.
Reuters correspondent Anthony Deutsch broke the story.>> What these test results found was that there are several markers or chemical traces matching that attack to a stockpile of chemicals that was in the hands of the Syrian government until 2014, when it was handed over to the international community for destruction.
So, in essence, this is the first time that chemical tests have shown that the sarin that was used to kill all those people, that chemicals in that sarin came from the government stockpile.>> Syrians have come to accept that chemical attacks are part of the conflict. Many of these local doctors training to deal with them responded to the chemical attack in Khan Shaykhun in 2017.
The tests also found the same markers were present in this one, and another near Aleppo in 2013, casting further doubts on government claims.>> Syrian officials, in the past, have denied repeatedly that they were involved in the chemical attack in Ghouta, or in any other chemical attacks during the Syrian war.
And they've argued that the attack, although it was in rebel-held territory, that the rebels themselves, the insurgents, had either stolen those chemicals, or made their own chemicals, and used them to carry out the attack.>> Syria's ally, Russia, also deny they carry out chemical attacks. But chemical inspectors say they found proof of an ongoing program, and that attacks like these are being ordered at the highest levels of government.
