Mexican President Claudia Sheinbaum promised on Sunday there would be justice for the brazen murder of a local mayor, Carlos Manzo, an outspoken critic of organized crime who had called on the government to do more to protect him and others.

Mexican President Claudia Sheinbaum ruled out a new "war on drugs" as a response to the assassination of a regional mayor who was shot at a Day of the Dead celebration, a brazen killing that has sparked national outrage.

The murder of Mexico’s most vocal anti-crime mayor shows that, despite President Claudia Sheinbaum’s crackdown on drug cartels, the battle is just beginning.

The mayor of Uruapan was assassinated on Saturday night during a Day of the Dead event in the city's main square.

Some see the security plan, which the Mexican president rolled out after the murder of the Uruapan mayor shocked the country, as more of the same ineffective politics.

President Sheinbaum stressed that violence should not be answered with more violence and said that actions must remain within the law.
