SOLYMONE BLOG: WHO FIGHTING WHOM IN SYRIA?

There has been an intense wave of Russian air strikes in two areas of Syria, activists say.Moscow says it is targeting jihadist groups like Islamic State in co-ordination with Syria's government.
Dozens of rebel groups have announced that they are breaking away from the main political opposition group - the Syrian National Coalition.
With so many individual rebel groups now operating across Syria, there are increasing reports of infighting and defection.

But Nato is worried some of the attacks are hitting rebel groups opposed to President Bashar al-Assad - some of whom are backed by the West.

So just who is fighting whom in Syria?
