A gas leak at a coal mine in Spain has killed six men and left five injured in the country’s worst mining accident in nearly 20 years.
The deadly methane gas leak occurred on Monday at the Santa Lucia quarry near the town of Pola de Gordon, AFP reports.
Emergency personnel evacuated five workers who were rushed to a hospital in the regional capital of Leon.
Trade union representative, Jose Antonio Colinas, said the gas leak happened so quickly miners had little time to put on protective masks.
"They really did not have time to react, the atmosphere was invaded by methane," he told reporters.
The mine, which is located 700 metres underground, is owned by Spanish company Hullera Vasco Leonesa.
Bloomberg reports there may be more workers inside the mine.
The accident is the worst at a Spanish mine since 14 miners were killed in 1995 due to a methane explosion at a coal mine in the northern province of Austurias.
A Spanish news site reports two of the country’s largest trade unions are calling for the Spanish mining sector to strike as a sign of respect for Monday’s victims.
