Could the deaths of 33 Turkish soldiers in Syria spark another refugee crisis in Europe?
Research fellow Luigi Scazzieri, from the Centre of European Reform (CER), told Euronews this could lead to "hundreds of thousands of refugees" arriving in the EU, and could see "a break down of its relationship with Turkey and greatly straining the EU's cohesion".
Meanwhile, Scazzieri said it was in Europe's best interests to "contain the crisis".
This can be done, he added, by increasing "support to refugees in Turkey and also pushing Russia to halt fighting in Syria."
