Research published by the UN’s Office on Drugs and Crime (UNODC) found that of the approximately 87,000 women and girls intentionally killed in 2017, about 58 percent died at the hands of someone who was either an “intimate partner” or a relative.

This amounts to six women being killed every hour by people they know, the report said. It was released Sunday to coincide with the UN’s International Day for the Elimination of Violence against Women. The campaign brought thousands of people to the streets of nations around the globe to raise awareness of gender-based violence.

Yury Fedotov, the UNODC’s executive director, noted that while the vast majority of worldwide homicide victims are men – accounting for 8 out of 10 homicides in 2017 – women bear the greatest burden in terms of violence perpetrated by intimate partners.
