A methane explosion at an ArcelorMittal coal mine in Kazakhstan on November 3 has left five dead and four others hospitalised, reported Al Jazeera.

Ruslan Imankulov, a spokesman for the country’s emergency ministry, said that “a sudden release of gas during the drilling of a drainage well” led to the explosion at the Lenin coal mine, according to the news organization. A total of 106 miners were rescued after the accident.

A government commission will investigate the incident and any potential violations of safety rules.

ArcelorMittal Temirtau, a unit of ArcelorMittal, operates several iron ore and coal mines in Kazakhstan as well as a steel plant.
