A French law has come into force in French Polynesia and New Caledonia requiring minors to be carrying an authorisation form from their parents if they cross a border alone.
The measure is reportedly aimed at curbing travel to recruitment areas of Middle Eastern extremists.
Minors now need a completed form as well as a photo copy of one of their parents' identity cards.
According to media reports, this means that minors travelling between France and French Polynesia and New Caledonia need the authorisation even if they only transit via Los Angeles or Tokyo.
