As the survivors are nationals of the country to which they are being returned, they probably don't need to be handed over to anyone, just the taxi driver for the ride home.
The "survivors" have already been fleeced of everything that they possess by inhabitants of the country to which you propose they be returned. For most the only things that they have left are their very lives. If they cannot be realised in fiscal form in the form of ransom then those 'assets' may well be written down to zero in the perfunctory manner prevalent there.
No, they are by no means all Libyan nationals, as you well know. I find your facile contribution to this enormous challenge grating, but then of course grammatical comment trumps that in your book.
To whom. Sorry, that just grates.
