Syria war: Who are Russia's shadowy Wagner mercenaries?

Russian mercenaries are reported to be in the thick of the fighting in Syria, helping President Bashar al-Assad's forces.

One shadowy group in particular, called Wagner PMC (Private Military Company), hit the headlines because of a clash on 7 February that resulted in dozens of Russian casualties.

The toll of dead and wounded is disputed, but it is still not clear why Russian irregulars attacked a base held by Kurdish anti-Assad forces and where US advisers were present. US forces retaliated with air strikes.
