He said evidence that terrorist groups have used sarin gas has been turned over to Russia and that Russia, through one of its satellites, has evidence that the rockets in the August 21 attack were launched from another area.
While the UN report did not lay blame, many experts interpreting the report said all indications were that the attack was conducted by Assad forces.
US, Britain and France jumped on evidence in the report especially the type of rockets, the composition of the sarin agent, and trajectory of the missiles to declare that Assad's government was responsible.
"The whole story doesn't even hold together. It's not realistic. ... We didn't use any chemical weapons in Ghouta," Assad said.
Assad said that his government would abide by an agreement reached with US and Russian officials to give up his chemical weapons. He says he has received estimates that destroying the stockpiles would cost USD 1 billion and would take roughly a year.
"We didn't say that we are joining partially. ... We joined fully. We sent the letter. We sent the document. And we are committed to the full requirement of this agreement,” he said.
He said that Syria was ready to talk to experts about the technical aspects of what he said would be a complicated task. He said Syria was ready to provide a list of weapons and provide experts access to the sites.
"We can do it tomorrow. It's not about will. It's about technique," he said.
While he said the August 21 attack was "despicable" and "a crime," he argued that no one had verified the credibility of videos or pictures of the victims.
"You cannot build a report on videos," he said. He later added: "There's a lot of forgery on the Internet."
He contended that opposition forces, which have been joined by extremist jihadists, could have gained access to sarin. "Sarin gas is called kitchen gas," he said. "You know why? Because anybody can make sarin in his house. Any rebel can make sarin. Second, we know that all the rebels are supported by governments. So any government that would have such chemical can hand it over."
