While cleaning it for the Olympic Games, France is trying to rid the Seine of its ghosts from the past. Last week, the French parliament's lower house passed a resolution condemning an infamous yet little-known massacre from 63 years ago, when Algerians were killed and thrown into the river.---On 17 October 1961, a peaceful demonstration in support of Algerian independence ended in tragedy: several demonstrators were beaten, killed and thrown into the Seine by the Paris police. This massacre took place in the final year of the war against French rule in Algeria.---The massacre was covered up for decades by French authorities. To this day, there is no precise information available concerning the exact number of victims. The official death toll is three, but some historians and activists believe that between 50 and 300 Algerians were killed that day.---It was not until 2021 that French President Emmanuel Macron acknowledged that “dozens were killed,” describing the police actions as “inexcusable crimes.” The resolution adopted last week by French lawmakers condemns it as “bloody and murderous repression,” yet the term “state crime” is absent from the text.
