Argentines are marching in the capital of Buenos Aires to condemn violence against women in a protest that is being echoed in other Latin American countries.

Wednesday's demonstration comes after the recent rape and killing of a 16-year-old girl.

Lucia Perez was found dead in the coastal city of Mar del Plata earlier this month. Authorities say that she had been drugged, raped and impaled by two men who have been arrested.

The rally is being organized on social media by women's groups under the slogan "Black Wednesday." Demonstrators are dressed in black to mourn the victims. A group of women also staged a brief strike as a sign of protest.

Similar marches against gender-based violence are taking place in Mexico, Bolivia, Chile, Paraguay and Uruguay.
