A devastating explosion at a busy supermarket in Hermosillo, Sonora, Mexico, has left at least 23 people dead and 11 injured, according to local authorities. The blast occurred on Saturday at a branch of the popular discount chain Waldo’s, sending shockwaves through the northwestern city and prompting an urgent investigation into the cause of the tragedy.

What Happened at Waldo’s in Hermosillo?

The explosion took place around 2pm local time (20:00 GMT) at the Waldo’s store located in a densely populated area of Hermosillo, the capital city of Sonora state. Emergency services were quickly dispatched to the scene, where witnesses described chaos and devastation as flames engulfed part of the building.

Images circulating on local news and social media show the storefront blackened by fire, with shattered glass and debris strewn across the surrounding area. Nearby businesses closed their doors in fear of the fire spreading, while paramedics, firefighters, and security forces worked to rescue survivors and recover the bodies of the deceased.

Authorities Rule Out Attack, Investigate Transformer Failure

Initial reports from the Sonora state prosecutor’s office indicate that the explosion was likely triggered by a faulty electrical transformer inside the store. Authorities have emphasized that there is currently no evidence of an attack or violent act targeting civilians, and that the incident appears to be accidental.

“Based on early investigations, the working theory is that the explosion resulted from an electrical malfunction involving a transformer located inside the building,” the prosecutor’s office stated.

Victims Include Minors, Community in Mourning

Sonora Governor Alfonso Durazo released a video message expressing deep sorrow over the tragedy. He confirmed that children were among the victims and assured the public that injured survivors are receiving medical care in Hermosillo hospitals.

“I have ordered a thorough and transparent investigation to determine the exact causes of this incident and hold anyone responsible to account,” Durazo said, adding, “No family will face this pain alone. Our emergency, security, and medical teams acted swiftly and with professionalism to control the situation and save lives.”

National Condolences and Federal Response

Mexican President Claudia Sheinbaum also responded to the incident, posting her condolences on X (formerly Twitter). “My thoughts are with the families of those who lost their lives in this terrible accident,” she wrote.

President Sheinbaum confirmed she has been in direct contact with Governor Durazo and ordered the Interior Ministry to send support to assist survivors and victims’ families as the community processes the tragedy.

Tragedy Strikes During Day of the Dead Festivities

The explosion took place during Mexico’s Day of the Dead (Día de los Muertos) celebrations, a cultural holiday during which families across the country remember and honor their deceased loved ones. The holiday typically brings crowds to local businesses and markets, potentially contributing to the number of people inside the store at the time of the blast.

Community Shaken, Investigation Ongoing

As authorities continue their investigation, the community of Hermosillo is left mourning an unexpected and heartbreaking loss. Local safety officials are urging other businesses to conduct safety checks as a precaution, especially concerning electrical infrastructure.

Families of the victims, many of whom were shopping during a holiday weekend, now face a tragic reality as they await further updates from the authorities.
