SPAIN – One person died and at least 25 others were injured on Saturday after a gas explosion in Madrid according to local reports.

The blast occurred in Puente de Vallecas district around 3 pm local time (1300GMT) and affected a commercial space that had been converted into a residence, the building above it, and a neighboring bar.

Carlos Marín de la Bárcena, chief of the Madrid City Fire Department, confirmed it was a gas explosion, though the exact type of gas, its cause or the precise location where it originated has not yet been determined.

The building has been evacuated and Madrid’s Deputy Mayor Inmaculada Sanz said residents of the nine apartments in the three-story building may need to be relocated for days due to “significant damage to the structural flooring between the ground and first floors.”

Sanz, the city’s head of Security and Emergencies, noted that the City Council is coordinating with Samur Social to provide temporary housing solutions to affected residents. Municipal technicians will now conduct a full structural assessment of the building.

Firefighters, working manually due to the instability of the structure, which makes the use of heavy machinery unsafe, have rescued four people from beneath the rubble.

Sanz indicated that much of the debris has already been cleared, and it now “seems unlikely” that more people are trapped.
