A gas explosion occurred late Wednesday night at the Plaça de Sants in Barcelona, injuring eight people.
The incident took place during construction work for the city's metro system, according to local reports.
Emergency services deployed nine fire crews to the scene to manage the resulting blaze and secure the area.
The blast was caused by a gas leak at the construction site.
Authorities have confirmed that all eight injured individuals are men.
There are no reports of fatalities or structural damage to surrounding buildings that would suggest a wider infrastructure failure.
