Protest marches have been taking place at least 20 cities across Mexico against the drug-related violence sweeping the country.
Thousands of people gathered in the main square in Mexico City chanting: "No more blood", the BBC reports.
Some also called on President Felipe Calderon to resign, saying his strategy for combating the cartels had worsened the violence.
The demonstrations were inspired by the poet and journalist Javier Sicilia, whose son was killed last week.
