Hundreds of thousands of women across Argentina, Mexico, Chile, Ecuador, Bolivia, the United States and other countries are slated to join a women’s strike today to protest violence against women. The protests come after the brutal rape and murder of a 16-year-old Argentine girl named Lucía Pérez earlier this month. The day’s protest are organized under the banner #MiercolesNegro, or Black Wednesday, and #VivasNosQueremos, or Alive We Want Us.
