Fighting is reportedly continuing in and around the Syrian city of Idlib, close to the border with Turkey.
Opposition groups say at least ten government soldiers were killed in an ambush by rebel fighters, and at least four civilians died in shelling by the Syrian army.
Footage shows the Free Syrian Army on Sunday trying to hold off a government offensive in Idlib by laying down explosives.
