The Mexican city mayor's private secretary and adviser was shot dead in a frenzy sunlight attack in the middle of the city.

Mayor Clara Brugada said her personal secretary Ximena Guzmán and adviser José Muñoz murdered the "direct attack". The motivation is under investigation, but Brugada promises that her administration will "continue to oppose insecurity."

The attack took place around 7 a.m. on a busy road in the modern block, near the entrance to the Xola Metro Station.

Initial reports suggest Muñoz is waiting in the street for Guzmán to pick him up.

The video from the security camera shows a man in a white top and a motorcycle-riding helmet waiting in Guzman's car, then suddenly pulling out his pistol and starting to fire - first in Muñoz, then Guzmán, and then running out of the screen. He and his partners reportedly fled nearby motorcycles.

It has the sign of organized crime strikes - a relatively rare event in the capital.

As Mexican city mayor, Brugada held one of the most powerful political positions in the country after President Claudia Sheinbaum, and they were allies to the Morena Party.

Sheinbaum condemned the murder and said in a morning press conference that there would be no punishment. Neither Guzmán nor Muñoz had any security details, but Sheinbaum said she didn't know there was any threat to them.

Guzmán has worked with Brugada for many years and is reportedly one of the closest people the government has come to her.

Shortly after the attack, Brugada dressed in black and paid tribute to the two victims in a nervous voice.

"(Guzma) is a great, relentlessly good woman. Since then, I have known (Muniz) … He is one of the smartest people I have ever met and very responsible." "I want to embrace their family, friends, loved ones and comrades in the struggle. We were shocked in the city cabinet and mourn for the loss of two dear comrades."

In a statement, Brugada said authorities were investigating the motivation and checking footage of surveillance cameras to identify the attacker.

Two hours after the attack, police had removed the body, while everything left was broken glass and dry blood in the morning sun.

Just on the way, a shoemaker said he was there when it happened.

He said: “I was working here when they shot and opened them, and I didn’t even realize it, and explained: “I’m a little deaf. ”

"But there was no panic," he added. "Everyone started to look that way, and then my friend here told me that two people died in the car."

"I didn't actually hear the camera, either," said a friend of the stall owner José Antonio. "I think it must be a silencer."

He added: "The killer didn't try to hide it - they did it during peak hours."

The murder was the highest profile attack on Mexico City government officials, assassination attempts were conducted five years ago on the city's then-copal police chief Omar García Harfuch.

In that attack, the gunman had connections with Jalisco's new generation cartel, ambushing García Harfuch, who left his home and killed three people with hundreds of bullets, but did not survive, and they survived to become the security ministers of the current federal government.

"We will not let this timid behavior be punished," García Harfuch wrote on X.

Stand owner José Antonio said at the crime scene that he had never seen anything like this in more than half a century.

"It's a peaceful community," he said. "They are targeted. I think for professional killers, whether there are people around or not. They do it and then get out of there."
