Production along Colombia’s second most important oil pipeline, the Cano-Limon Covenas, has been suspended following two rebel bomb attacks, UpStreamOnline reported.

The twin attack on the 780km pipeline was carried out by National Liberation Army (ELN), rebels in rural areas in the northern Norte de Santander and Arauca provinces, Reuters reported citing state oil company Ecopetrol as a source.

The pipeline can transport up to 210,000b/d of crude from Occidental Petroleum oil fields near the Venezuelan border to the Caribbean port of Covenas.

Attacks by the ELN on oil installations have been a frequent occurrence during a conflict that has taken more than 220,000 lives and displaced millions over the past 52 years.

The Revolutionary Armed Forces of Colombia (FARC), the biggest rebel group in the South American country, declared a unilateral ceasefire in July 2015 as it negotiates a peace accord with the government. The FARC has stopped its attacks on pipelines, however, it was infamous having blown up a pipeline in a series of assaults over a two-week period last year that had left 32 security workers dead and dozens more injured.
