Syrian regime steps up offensive on Idlib

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.
