Not sure EXACTLY who I would point the finger at but there is extensive GPS jamming and possibly spoofing going on between Cyprus and the coast of Lebanon/Syria. I have suffered several GPS outages in the area. More worrying, on one occassion we had apparently correct but different positions from both the GPS units. Theis resulted in the Capt and FO FMS positions in disagreement by 15 miles.
I now disable GPS updates in that area.
