Nine individuals sustained injuries following an explosion in Acapulco’s central square, authorities reported on Monday.

Prosecutors in Guerrero, the southern state where Acapulco is located, did not disclose the cause of the explosion, which occurred late Sunday. However, burns sustained by some of the injured suggest the involvement of an incendiary device. A baby among the victims was reported to be in critical condition.

Officials did not specify whether the victims were local residents or tourists, although the square, lined with restaurants, is frequented by both. The statement emphasized that authorities were “taking care of Acapulco residents as well as tourists, following the incident.”

Acapulco, which was severely impacted by Category 5 Hurricane Otis in October, has a history of violent incidents.

In late May, the bodies of six individuals – four men and two women – were discovered strangled and discarded in a pile in Acapulco. The bodies were found on a street with their hands bound behind their backs. The preceding week, five dismembered bodies were found scattered on a street in Acapulco. One of the victims was a candidate for a town council position in the nearby town of Coyuca de Benítez.

While Acapulco has experienced violence, these incidents typically involve targeted attacks or the discovery of small groups of bodies in public spaces. Mass indiscriminate attacks on pedestrians in town squares remain relatively uncommon.

Acapulco continues to grapple with recovery efforts following the devastation caused by Category 5 Hurricane Otis in October. Otis resulted in at least 52 fatalities and caused extensive damage or destruction to most hotels in the area.
