Several papers wonder what the West's reaction to the situation will be, particularly - as the Guardian reports - since Islamic State militants "have seized four more hostages near Aleppo in recent days, taking to more than 20 the number of foreigners they now hold". The Financial Times points out that air strikes might have limited impact , given IS fighters can hide among civilians and use them as shields. A Kurdish commander tells the paper: "IS never settle a front for us to fight or to attack. They don't have any lines where they set up weapons. It doesn't feel like fighting a battle. They never fight on foot and are always in vehicles, so very quick."
