Russian plane shot down in Syria, page-21

The plane could not have been hit by Syrian AA as it it dropped from radar 35km from the coast. So the only options are

1) Syrian SAM
2) French SAM
3) Israel AAM
4) Israel SAM

As Syrian and Russian radars and systems are now 100% linked I call bs on point 1.
I doubt it was an Israeli SAM so that leaves either direct air interception by the Israeli criminals or surface launch by the French criminals.
