The Valentine's Day demonstration, led by women, was sparked by the killing of 25-year-old Ingrid Escamilla in Mexico City and the publication of graphic photos of her mutilated corpse in newspapers.
The protesters, numbering at least 200 and comprised mostly of women, burned vehicles belonging to La Prensa and briefly clashed with security forces who prevented them from entering the newspaper's offices.
Chanting "not one more murder" and carrying signs saying "we demand responsible journalism," "Ingrid we are all you" and "sexism kills," the demonstrators demanded justice.
An average of 10 women a day are killed in Mexico. Last year marked a new overall homicide record, official data shows.
