The head of Syria's main opposition group has said he will attend planned peace talks in Geneva in January aimed at ending the civil war.
Ahmad Jarba said the Syrian National Coalition saw talks as a step towards "leadership transition", meaning President Bashar al-Assad's removal.
The Syrian government has also said it would attend but would not negotiate a handover of power.
Rebel groups involved in the fighting have said they will not take part.
Heavy clashes were reported on Thursday in eastern Damascus and Golan in the south-west. Activists reported six dead after a surface-to-surface missile fell on the jihadist-controlled northern city of Raqa overnight.
