Syrian President Bashar Assad believes that by being passively supporting the al-Nusra Front and Islamic State terrorist groups, Turkey is playing a most destructive role in the Syrian crisis.

“Turkey is playing a most negative role in our crisis. That’s related directly to [President Recep Tayyip] Erdogan himself and [Prime Minister Ahmet] Davutoglu, because they both reflect the real ideology that they carry in their hearts, which is the Muslim Brotherhood ideology,” Assad said in an interview with the French newsmagazine Valeurs Actuelles on Thursday.

The Syrian leader emphasized that, compared to Saudi Arabia and Qatar, Ankara was playing the most dangerous role in general, by giving all possible assistance to the terrorists.

“Some countries support the Nusra Front, which is al-Qaeda, some other countries support ISIL, while Turkey supports both and other groups at the same time. They support them with, human resources. They support them with money, logistics, armaments, surveillance, information, and even the maneuvers of their military through their borders during the fights in Syria."

"Even the money that’s being collected from the rest of the world passes through Turkey, and the oil that ISIL sells is through Turkey, so Turkey is playing the worst part of our crisis,” Assad was quoted as saying by the Syrian news agency SANA.
