During the Algerian War of Independence (1954–1962) most French politicians came to accept the need to grant Algeria its independence. Only the Organisation armée secrète (OAS; Secret Armed Organization) continued to resist independence. The Left called for a demonstration on 8 February 1962 to denounce the OAS and the Algerian war. The Paris Police, led by Maurice Papon, repressed this demonstration, as it had done on 17 October 1961 (when between 32 and 200, mainly Algerian people, are estimated to have been killed). Police blocked nearby streets at both ends before charging the crowd. Demonstrators tried to take refuge in the entry of the Charonne metro station, but police pursued the crowd into the station and hurled heavy iron plates (used around the bases of trees and on metro vents) down onto demonstrators in the stairwells. Eight people were crushed to death or died from skull fractures and a ninth died from wounds in hospital. All of the dead, except a sixteen-year-old boy, were Communist Party or union members. Police blamed the violence on the demonstrators. A massive funeral demonstration drew between a quarter and a half million participants. The dead are buried in the Père Lachaise Cemetery near the "Mur des Federes". A ceremony at a memorial plaque in the station is held each February 8.
