Salomé, 21, could be France's 100th victim this year of "femicide" - usually defined as the murder of a woman by a partner, ex-partner or family member. The day after Salomé's body was found, a 92-year-old woman was caned to death by her 94-year-old husband.

Within hours, the French government announced a raft of measures to protect women from domestic violence. Other European countries have already reacted to a crime that knows no borders or social class, but the picture across the continent is mixed.
