So far, four of the seven suicide attackers have been identified as French nationals. Three of the four are believed to have spent time in Syria and Iraq.

France is particularly vulnerable to terrorist activities carried out by its own citizens; it has the biggest contingent of European fighters in the Syria and Iraq conflict zone
The slaughter in Paris caused shock, but not surprise. In January, terrorists targeted the satirical magazine Charlie Hebdo and a Jewish grocery store; two of the three perpetrators were returning fighters with ties to al-Qaeda and IS.
France is particularly vulnerable to terrorist activities carried out by its own citizens; as home to Europe’s largest Muslim population, numbering some five million, it has the biggest contingent of European fighters in the Syria and Iraq conflict zone. According to French authorities’ most recent estimates, as many as 2,000 French nationals have been implicated in jihadist networks. Moreover, 571 French citizens are fighting for Islamic State or other terrorist groups, 141 have died there, and 246 have returned home.
