After Putins accusation that Turkish President might have bought dirty oil, this
Al Jazeera report about the syrian's oil might be interesting.

Somewhere the oil must go over the traders if not to turkey, damaskus, rebells in the land perhaps to israel, america or russia, libanon? One thing is sure, they would not pour it out unto desert sand or burn it off, thats for sure. Some have a profit, perhaps the false. Some guys earn monthly salary for the livelihood with that dirty oil. Somebody trades with the oil. If the Daesh regime has become rich with oil trade someone has bought the oil and has had profit, someone is interested that the trade is not interrupted.
Rumours say the son of turkish president (he always gets passed the buck) benefits from oil trade in syria and that rumor is of course not affirmed, and that even worse he had given order to shoot down the jet, absurd, as if he "was" daesh oil minister and of course this is not attestable. If such infam accusations would be ever true the president would resign and talk with his son to stop that dirty game, but anyway he would not be the only trader who gets rich with oil, there are thousand others who take the oil and like it although it is dirty. Oil has no bow tie.
