Five individuals have died and four others were reported seriously injured following an explosion at the Cerredo coalmine in Degaña, Asturias, on Monday.

The tragic incident occurred approximately 450 kilometers (280 miles) northwest of Madrid, with local emergency services confirming the details.

Initial reports indicated that two workers were missing; however, it has since been established that all personnel have been accounted for.

The exact cause of the explosion remains unclear, though emergency services were alerted to a potential issue involving machinery at the site.

Local media outlets report that the explosion was linked to a malfunction of a machine.

Those injured in the explosion were promptly transported to hospitals in nearby cities; two of the injured were evacuated by helicopter due to the severity of their conditions, which included burns and, in one case, a significant head injury.

Reacting to the tragedy, Spain's Prime Minister, Pedro Sánchez, expressed his heartfelt condolences to the victims' families and extended wishes for a swift recovery to those injured via a message posted on social media platform X.

In a further response, Adrián Barbón, the head of the regional government of Asturias, announced a period of mourning lasting two days to honor the deceased.

Mining has historically been a crucial industry in Asturias, contributing significantly to the region's economic landscape.

This incident resonates profoundly, recalling the devastating 1995 explosion near Mieres, which resulted in 14 fatalities.
