The Paris massacre of 1961 occurred on 17 October 1961, during the Algerian War (1954–62). Under orders from the head of the Parisian police, Maurice Papon, the French National Police attacked a demonstration by 30,000 pro-National Liberation Front (FLN) Algerians. After 37 years of denial and censorship of the press, in 1998 the French government finally acknowledged 40 deaths, although there are estimates of 100 to 300 victims. Death was due to heavy-handed beating by the police, as well as mass drownings, as police officers threw demonstrators into the river Seine.
