I think that our colleagues at UNHCR have developed very helpful guidelines on unaccompanied minors. Perhaps Michael can speak to that later. There's also Save the Children.
I would say also that Europe is much more advanced in terms of tools and policies for unaccompanied minors because it receives many more unaccompanied minors at its borders. They are coming through the Middle East. There has been much more work done in the European Union and in the U.K. on this issue.
