Two of the nine were not - they were actual, recent immigrants through asylum-seeking process.
"Ahmad al-Mohammad" who came as a refugee through Turkey to Leroa in Greece, and together with him were registered the fingerprints of another immigrant known as "M. al-Mahmodin".
The rest were second-generation immigrants:
Bilal Hadfi was French but he spent time in Syria and came back, not through controlled border crossings, so he might have come with the asylees/immigrants. Others included French citizens Samy Amimour, who fought in Yemen, and Omar Ismail Mostefai and Foued Mohamed-Aggad who fought in Syria, and they were on wanted lists but were not spotted on border, so they appear to have come through people smugglers as well.
