More about the black boxes.
And PLEASE note the wording in the original text, my translation is only a translation.
Crash dans le Sinaï : l'attentat confirmé par les boîtes noires - Le Point
Selon la source citée par l'Agence France-Presse, les photos des débris montrent que certains sont criblés d'impacts allant de l'intérieur vers l'extérieur de l'appareil, « ce qui accrédite plutôt la thèse d'un engin pyrotechnique ».
My translation:
The source* cited by AFP expressed that the photos of debris had certain impact damages on the interior versus the exterior of the airframe << that very well could credit the hypothesis of a pyrotechnic event** >>.
*in context, this source seems to be the same source cited earlier, I made a translation of that a few pages ago.
**engin can mean both "engine" and "method by which something is driven/propulsed in the wanted direction"
