Buenos Aires, Argentina—Emergency crews converged on a residential apartment building in Buenos Aires on July 7, 2026, after a natural gas explosion rocked the structure. Three people sustained injuries in the blast. The explosion occurred during the mid-morning hours, damaging several units across the second floor.

Firefighters arrived to find smoke pouring from the building’s shattered windows. They initiated an immediate evacuation of all residents. The force of the blast blew out brick walls and scattered debris across the sidewalk below.

Paramedics stabilized the three injured residents before transporting them to a local hospital. Officials reported that the victims suffered from burns and lacerations. They remain under observation but are expected to recover from their wounds.

Specialized gas safety teams entered the building to shut off the main supply lines. They noted a strong odor of mercaptan lingering in the stairwells. Technicians are currently testing internal pipes to find the source of the leak.

Police cordoned off the block to protect the public from the threat of further collapses. Residents gathered behind the safety tape, waiting for news regarding their property. Many have been unable to return to their homes while the inspection continues.

A representative for the city’s emergency services confirmed that the structure remains stable for now. However, he cautioned that structural engineers must conduct a full sweep before occupancy resumes. Investigators are documenting the damage to each apartment affected by the blast.

Neighbors reported hearing a muffled boom followed by the sound of glass falling. Some claimed they had notified the utility company about a possible leak earlier in the week. These reports are now a core part of the ongoing investigation.

Work will continue through the night to secure the site. Inspectors plan to interview building management regarding recent plumbing or gas maintenance. No additional casualties were found during the secondary sweep of the premises.
