Mexican authorities are investigating the killing of a mayor in San Miguel Amatitlan, Oaxaca, in the country's latest case of political violence.
Joel Bravo Martínez was gunned down on Saturday, weeks after he reported that he feared for his life and requested protection from the state government, according to a statement from his party PAN.
The Oaxaca state prosecutor's office said in a statement that once it learned of the killing, the institution "immediately activated the protocols for the investigation of crimes of high impact".
