Argentina—An elderly couple died this morning in a house fire sparked by a malfunctioning indoor heater. Firefighters were alerted to the blaze by neighbors who noticed smoke billowing from the windows of the small suburban home. Despite a rapid response, the fire had already engulfed the living room where the couple was located.

The heater, an older model, appears to have shorted out and ignited nearby curtains. The speed at which the fire spread prevented the residents from reaching the exits. Fire investigators found no evidence of foul play, pointing instead to the catastrophic failure of the electrical unit.

The tragedy has prompted a wave of concern among local seniors. Many households in the district utilize similar heating equipment that has not been serviced in years. Municipal authorities are urging residents to have their heating systems inspected immediately to prevent further loss of life during the cold season.

Social services are currently assisting the surviving family members of the victims. The home is a total loss, and the investigation into the cause is now focused on whether the heater had been subject to a recent recall or maintenance error. The remains were transported to the local morgue for standard examination.

The neighborhood is mourning the couple, who were well-known and active in the local community. The police have cleared the scene, but the charred structure will remain fenced off for several days. Investigators are conducting a final sweep to ensure no other hazards remain in the building.

This event is the latest in a series of domestic fires reported this week. Public safety officials have launched a televised campaign to educate residents on fire hazards, specifically emphasizing the danger of leaving heaters unattended overnight.

The final report on the incident will be presented to the local district attorney once the technical examination of the heater's remnants is finished. The house remains a somber site as the investigation continues into the electrical wiring of the property.
