In the past week Western nations have ramped up the intensity of their attacks on Da'esh, with France increasing its air strikes and David Cameron pledging to also strike Da'esh positions in Syria. Meanwhile, further gains have been made by resurgent Assad regime forces, backed by Russian air strikes.
