There seem to have been lots of emotional responses above which is understandable, but the problem needs to be approached with reason.

It's not possible to return asylum seekers to their port of origin if that port (country) refuses to allow them back in.

stop wishing for it; stop demanding it; deal with it using reason and of course, diplomacy.

It is necessary to establish the credentials of people who claim to have lost their documents but must have had some documentation on arrival at their port of departure.

This is also a matter for co-operation between the authorities of the countries involved.

It's a frustrating, emotional issue, but we need to be careful that our response remains in the realm of the reasonable and the humane.
