Don't know. Brief clips I saw on TV news of the crash site showed heavily burning wreckage. Also, the crash debris appeared to be scattered over a wide area, suggesting aircraft breakup in flight.
When a plane runs out of fuel, it goes pretty much straight down, and the wreckage is found in a relatively compact area. That's the way it was in the Payne Stewart accident. That's the way it was with the hijacked plane that crash in Pennsylvania on 9/11/01 (although that one was deliberately forced straight down vs. running out of fuel).
I suspect governments and the airlines don't want to admit to Islamofreak hijackings and crashes anymore because of the impact to the aviation industry. Remember the three Russian airliners that were hijacked almost simultaneously a few years ago? The Russians tried every which way to claim they were accidents.
