International inspectors have begun destroying Syria's stockpile of chemical weapons and the machinery used to create it, the UN has said.
The official was unable to confirm what specifically was destroyed, but said that by the end of Sunday a combination of both weapons and some production equipment would be put out of order.
He spoke anonymously because of the matter's sensitivity.
Inspectors are tasked by the UN to dismantle and ultimately destroy Syria's chemical weapons programme by mid-2014.
The push to destroy Syria's chemical weapons programme came after an August attack near Damascus that killed hundreds of civilians.
