Further escalation occurred from August to October 1961 as the FLN resumed bombings against the French police, and killing 11 policemen and injured 17 (in Paris and its suburbs). This culminated on 17 October 1961, when the French police suppressed a demonstration by 30,000 Algerians who were ostensibly protesting against a de facto curfew imposed on them by the prefecture of police, though the FLN had planned the demonstration as a potential provocation as well.[33] While estimates differ, the number of dead officially acknowledged (in French government reports and statements of 1998) in putting down this demonstration was 40 to 48. Some protesters may have been tortured before being killed and having their bodies thrown in the Seine.[36]
