Four members of a French family died after jumping from a seventh-floor apartment in the Swiss town of Montreux, police said. A man aged 40, his 41-year-old wife, her twin sister, the couple’s eight-year-old daughter and their son all lived “withdrawn from society”, according to police. The police said that “since the start of the pandemic, the family was very interested in conspiracy and survivalist theories”. The family lived in virtual self-sufficiency having amassed a stockpile of food, taking up much of their living space but enabling them to see out a major crisis. A close friend of the French philosopher Albert Camus, Feraoun was assassinated in Algiers in 1962 by a far-right French pro-colonial group.
