They start from the same point, in Russian media poor fuel is one

The obvious problem with that idea is that poor fuel would usually
just stop the engines, leaving them 30,000 feet or so of gliding
descent in which to report their difficulties and attempt power-off
landings.


Gas turbines are pretty tolerant of fuel quality and
if this was the problem I'd expect a lot more than 2
aircraft to be affected.
