The downing of a Syrian jet by Turkey was not an isolated incident but part of a major offensive by Al-Qaeda affiliated groups Al-Nusra Front (designated a terrorist organization by the US State Department) and Ahrar Al-Sham against a northwestern Syrian-Turkish border crossing.
Turkey has been supporting Al-Qaeda’s attack on the Kasab border crossing, the only crossing that was still held by the Syrian military. While the AFP did report that the group involved in the attack was the Al-Qaeda faction Al-Nusra Front, this fact has not made it to any mainstream media headline.
Al-Nusra Front militants are actively being given safe haven by Turkey. The map below shows the Al-Qaeda Camp within the Turkish border from which the attack on the Kasab border crossing came. Al-Qaeda militants also brazenly videotaped themselves walking right through the Turkish Kasab border gate into Syria without any harassment from Turkish guards.
