"We targeted a training camp where there were foreign Daesh fighters trained to come and attack us in France," a ministry source said, using another acronym for Islamic State.
"Among them, there were French nationals and French speakers. We were targeting foreign fighters, not French nationals in particular."
French intelligence learned of the presence of the foreign fighters at the camp by questioning jihadists linked to Syria, the source added.
The Journal du Dimanche (JDD) newspaper first reported the presence of "several French citizens" and other francophones among the hundred or so jihadists at the sprawling camp, which lies five kilometres (three miles) southwest of Raqa, the Syrian town widely considered to be IS's centre of power.
