This "incident" (if it is true) supposedly took place in Yemen, rather than Syria, so they may be totally irrelevant to the discussion.

The Foreign Intelligence Service (SVR) is reporting today that a raid to remove from Yemen the two captured Central Intelligence Agency (CIA) “assets” who are believed to have masterminded the downing of Flight 9268 over Egypt last Saturday, utilizing Islamic State (ISIS/ISIL) terrorists, was “highly successful”, and once the Aerospace Forces “protected/guided” aircraft returned to Federation airspace, President Putin banned all aircraft flights to this region on the advice of Federal Security Services (FSB) Director Aleksandr Bortnikov.

...

After the capture of these two CIA “assets” and their “highly sophisticated” equipment, this report continues, a Ministry of Emergencies (EMERCOM) “special flight” was dispatched to Yemen’s capitol of Sanaa where it landed successfully by using as cover one of the most powerful cyclones to hit this nation in its entire history.

Upon this EMERCOM “special flight” landing in Sanaa, this report says, the two CIA “assets” and their equipment, along with the Spetsnaz troops that captured them, then boarded the plane but were refused to be allowed to take off again by Saudi military aircraft who under Obama regime control are bombing this nation into utter and complete famine.

Within hours though, this report states, Aerospace Forces “countermeasures” employed against the Saudis was successful thus allowing this EMERCOM “special flight” to depart from Sanaa and return safely to Federation airspace.
