A shift in altitude and position is normal in FR24. A horizontal shift by 4 km would be a lot, but not unheared of.
All this data tells us, is that the approach was stable until the very end of the transmitted data.
Do we know by now whether this has been an ILS approach or a GPS approach?
All reports say go-around, at least one engine is missing all its fan blades, looks like a crash at full power (of at least one engine, to be exact). Post impact fire shows plenty of fuel was left. The rest is gueswork from here. Maybe locals know more.
