Of course it was Ex-Cairo before CDG, it's an Egyptair aircraft ! They don't have rights to fly Asmara - Tunis - Paris - Cairo. When they say it had been to Tunis and Asmara before this flight I think there's an assumption of a degree of understanding that what is meant is the aircraft flew from Cairo to Asmara and back, then Cairo - Tunis and back then to Paris and was on the return leg to it's home base when it disappeared.
