Syrian government forces have taken control of the north-western city of Idlib, after days of clashes with rebel fighters, opposition activists say.
Security forces are now reportedly carrying out house-to-house searches in the area, which has been a stronghold of the Free Syrian Army (FSA).
It is not clear where the rebels have gone, or how many people have died.
Meanwhile, the UN envoy to Syria has said President Bashar al-Assad has sent a response to a proposed peace plan.
Kofi Annan was considering the reply and would have more to say later on Wednesday, a spokesman in Geneva told reporters.
