A new study is warning more than a third of women worldwide are victimized by sexual or physical assault from a partner. Unveiling the findings, Dr. Claudia García-Moreno of the World Health Organization said violence against women is a global epidemic.

Dr. Claudia García-Moreno: “This report for the first time brings together data on the prevalence of different forms of violence against women, and it shows that the problem is widespread and it’s unacceptably high. One in three women globally are affected by either physical or sexual violence from a partner or sexual violence by a non-partner. Violence against women is a global problem that it is widespread and occurs in all regions at unacceptably high levels.”

According to the study, 40 percent of women killed worldwide were slain by a partner.
