A bomb attack over the weekend by the Marxist ELN rebels has halted the flow of crude along Colombia’s second largest oil pipeline, the Cano-Limon Covenas, sources from the military and state-run oil company Ecopetrol said on Tuesday.
The explosion took place on Saturday in a rural area of Saravena municipality, in the province of Arauca. Though the 485-mile (780-km) pipeline, operated by U.S.-based Occidental Petroleum Corp was stopped, operations at the Cano Limon field and exports were unaffected.
Attacks on oil infrastructure by the National Liberation Army, or ELN, have been frequent during the group’s five-decade war with the government. There have been 32 bombings so far this year, according to Ecopetrol, and frequently cause environmental damage.
