"We want Peace," says a huge white banner in the town of Teorema in the Catatumbo region, where at least 80 people have been killed and 40,000 displaced in a turf war linked to the cocaine trade. The bloodshed in the area bordering Venezuela has been blamed on the leftist National Liberation Army (ELN), which is accused of going house-to-house in towns and villages to kill dissident members of the defunct FARC guerrilla army and their sympathizers. The ELN's attacks, which began on January 16, blindsided the government of left-wing President Gustavo Petro, who had been in on-off peace talks with the biggest rebel army in the Americas and is threatening the group with "war."
