The attack earlier this month appeared to confirm that Assad had held onto some.
Ahmet Uzumcu, director-general of the Organisation for the Prohibition of Chemical Weapons, said on Wednesday that the results "from four OPCW-designated laboratories indicate exposure to sarin or a sarin-like substance". "They had at least 2,000 tons".
Sakat, 53, said he defected after being ordered to use chemical weapons on Syrian civilians. Rather, it was to deter future chemical attacks.
The United States launched 59 cruise missiles in a strike meant to damage the infrastructure of the airstrip from which the USA believes the chemical weapons attack was launched. But when Assad used the chemicals on his own citizens, Sakat declared, "I could not stand and watch the genocide".

Hamish de Bretton-Gordon, a former commander of the British military's chemical weapons unit who is now assisting Syrian NGOs, said that he estimated that Assad retained 200 tons of chemical weapons, but felt that Sakat's estimate of 700 tons was "plausible".
A USA official says that Syria has moved all of the aircraft from the airbase that was struck by US missiles two weeks ago to an airbase used by Russian Federation for missions within Syria.

The Khmeimim base, along with a naval facility in Tartus, is one of the two of the primary Russian military installations in Syria.

'We have elements that will enable us to show that the regime knowingly used chemical weapons, ' he said.
Russian Federation is Syria's most powerful ally and has bankrolled much of the six-year conflict, carrying out regular airstrikes in Syria to prop up Assad's regime. He spoke to The Telegraph from an undisclosed location in Europe.
Asked by CNN whether its evidence amounted to proof that the Syrian regime carried out the attack, the OPCW said that it was still investigating the incident. Its investigations and conclusions provide vital independent, third-party evidence on violations of the Chemical Weapons Convention, for the global community to decide upon action.
A senior Israeli military officer, in a briefing to Israeli reporters, said "a few tonnes of chemical weapons" remained in the hands of Assad's forces, a military spokesman told Reuters.
