Ammon News - A fire and explosion at a discount store in northwestern Mexico on Saturday killed at least 23 people, including children, and injured 12 others, state authorities said.

The fire occurred in downtown Hermosillo, the capital of Sonora state, Sonora Gov. Alfonso Durazo said in a video posted on social media.

Sonora Attorney General Gustavo Salas Chávez provided the death toll and said the injured were taken to six hospitals in Hermosillo.

Salas Chávez said preliminary investigations showed the deaths were caused by “inhalation of toxic gases.”

“At this time we have no indication that leads us to presume the fire was intentional,” he said, noting authorities had not ruled out any line of investigation.

"My heartfelt condolences to the families and loved ones of those who lost their lives," President Claudia Sheinbaum said in a post on X, adding that she had directed support teams to be sent to help victims' families and the injured.
