Cerrejon, Colombia's largest coal mine and a unit of Glencore, suspended train operations on August 13 after an explosives attack damaged its rail line in the northern department of La Guajira, Reuters reported.
The attack occurred shortly after midnight near kilometer 125 of the 150-km railway carries thermal coal from the open-pit mine to Puerto Bolivar on the Caribbean coast for export. No one was injured, the company said in a statement.
Authorities were inspecting the area while Cerrejon assessed damage to the infrastructure. The company said it was the fifth attack on its facilities so far this year, though it did not speculate on who might have been responsible.
Cerrejon, which employs more than 12,000 workers, has faced repeated disruptions from protests by Indigenous communities and bomb attacks on its railway. Communities near the mine have accused Glencore of environmental damage.
The mine produced 16.8 million tonnes of coal in 2025, down 12.5% from 19.2 million tonnes in 2024. The rail line is critical for moving export volumes to Puerto Bolivar, where up to 40 million tonnes of thermal coal are shipped annually, and any prolonged suspension could affect those shipments.
