Michoacán state Mayor Carlos Manzo, who called for a take-no-prisoners approach to Mexico's drug cartels, is slain while marking the Day of the Dead holiday.

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

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.

Trump has declared war on Latin American drug traffickers and declared the Sinaloa Cartel a "terrorist" organisation. He has sent several warships toward nearby Venezuela, accusing the government of being part of the drug trade, and ordered a missile strike on a suspected drug boat, killing 11 people.
