Government forces in Syria are stepping up their offensive against opposition fighters in their largest remaining stronghold.
Idlib is supposed to be a "de-escalation zone" - set up last year with the backing of Russia, Iran and Turkey.
But the deal appears to have crumbled: President Bashar al-Assad - backed by Russia - is bent on regaining control of the area, to cement his grip on power.
For civilians, the onslaught is causing misery in freezing winter conditions.
