As much as I regrett any loss of life, particularly by violent means, and sympathise with the Palestinian cause, I think this is a clear example of why every student pilot has to pass his/her air law exam before going solo.
In any case, and without knowing the details (I doubt anybody will ever do), let's assume he was lost, let's assume he didn't know the interception procedures, still, didn't he have a radio to communicate on 121.5? Too many mistakes in such a "hot" area is a sure recipe for death.
My condolences to his family and friends.
