Reporting from Mexico City, Al Jazeera?s John Holman said there had been 50 political murders in the country in the first three months of the year alone, though political killings are relatively rare in the capital.

Mexican president vows justice

Mexican President Claudia Sheinbaum, a Brugada ally who previously served as the capital?s mayor, expressed condolences over the killings and said her government would ensure that ?justice is served?.

?We express our solidarity and support for the families of these two individuals who have worked in our movement for a long time,? Sheinbaum said.

?We know them, we stand with their families, and we will give her [Brugada] all the support the city needs from the Mexican government.?
