As Russia mourns the death of its ambassador to Ankara, Turkey's president is blaming supporters of US-based cleric Fethullah Gulen for the murder. But considering the assailant shouted: "don't forget Aleppo, don't forget Syria", we ask our panel what, or who, might have motivated the off-duty policeman. How much of it is related to Syria? And are Erdogan's priorities shifting? Just when Turkey and Russia had buried the hatchet, does the assassination make Turkey's president beholden to Moscow?
