German prosecutors say 10 people have been charged with negligent manslaughter and causing bodily harm over the 2010 Love Parade stampede in which 21 people including an Australian woman were killed.
Those charged are four staff of the techno music festival organiser Lopavent and six members of the administration of the western city of Duisburg, said the city's chief prosecutor Horst Bien on Wednesday.
"An event where people wanted to party, dance, have fun turned into a terrible tragedy," Bien told a press conference.
"Twenty-one people had to die, hundreds were injured.
"The victims, their relatives and the bereaved are still suffering today because of the traumatic events."
In the tragedy on July 24, 2010, a large crowd of revellers at one of Europe's top techno events was forced to go through a narrow tunnel that served as the only entrance and exit to the festival grounds in the industrial city.
Those killed - 13 women and eight men who were crushed, trampled to death or suffocated - included a 27-year-old woman from New South Wales and six other foreigners from Italy, the Netherlands, China, Bosnia and Spain.
More than 500 were injured.
