The 1961 Paris massacre was the mass killing of Algerians who were living in Paris by the French National Police. It occurred on 17 October 1961, during the Algerian War (1954–62). Under orders from the head of the Parisian police, Maurice Papon, the 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 government finally acknowledged 40 deaths, while some historians estimate that between 200 and 300 Algerians died. Death was due to heavy-handed beating by the police, as well as mass drownings, as police officers threw demonstrators into the river Seine.
