Cenit, a subsidiary of Colombia's state-controlled oil company Ecopetrol, reported five attacks on Monday targeting two major pipelines, the Cano Limon-Covenas and Bicentenario.

Three blasts hit the Cano Limon-Covenas, which transports crude oil from fields near the Venezuelan border to the Caribbean coast, while the Bicentenario pipeline suffered two attacks, according to a Cenit statement.

The company did not specify when all the attacks occurred, but local media reported a plume of smoke rising from the Cano Limon-Covenas pipeline on Monday. Although the company did not immediately identify the perpetrators, leftist rebel groups in Colombia have a history of targeting oil infrastructure.

Military personnel were deployed to secure the areas where repairs were undertaken. Despite the attacks on major pipelines, the company spokesperson assured that exports were not impacted.

Colombia's oil pipelines are vulnerable not only to violent attacks but also to theft by criminal gangs who siphon oil for illegal refining and use in the drug trade. 

The country's other major pipeline, the Trasandino, remains shut down as part of an ongoing strategy to combat oil theft and is expected to remain offline through the end of 2024.
