Three men suspected of joining Islamist militants in Syria gave themselves in to French authorities on Wednesday after a day of high confusion which exposed security shortcomings in France, including poor collaboration with NATO ally Turkey.
Turkish authorities put the three men on a plane bound for Marseille on Tuesday after the pilot of an earlier flight to Paris had refused to let them board because they lacked necessary documents.
Compounding the confusion, the French Interior Ministry then said they had been arrested on arrival in Paris and had been charged with being linked to a terrorist organisation.
It later admitted this was not the case and said the French intelligence services had only been informed of their arrival after they had entered France
"The Turkish initiative to change the plane was unfortunate," Le Drian said, adding the passport control system in Marseille
had not been working, as is "often the case".
