Su-24 downed...

[Edited] News emerge that Turkey defence apparatus down Russian’s Su-24 near the Turkish-Syrian border. Open source reported that one of two pilots was killed and the position of another one is unknown. 

Turkish statement says that it had issued 10 warnings over five minutes but Russian pilots refused to take it seriously. At the same time President Putin warned that the downing of Su-24 would have "serious consequences for Russia's relationship with Turkey." 

Despite Russia and Turkey have close trade relationship but national pride and sovereignty may drive these two country into an open war. International war media also have reported that NATO has called for emergency meeting.

Will this incident drive military powers for another war in Europe?
