The head of the task force in charge of eliminating Syria's chemical weapons says Damascus still holds about 7.5% of its 1,300-tonne stockpile at one site.

Envoy Sigrid Kaag urged the Syrian government to meet a Sunday deadline to remove its arsenal from the country.

All Syria's chemical weapons are scheduled to be destroyed by 30 June.

It comes as the US expressed concern over reports that Syrian forces had used chlorine gas as a weapon.
