Tensions between Colombia and Venezuela have escalated after a leaked military intelligence report revealed that rebels responsible for one of Colombia's deadliest attacks in recent years traveled through Venezuelan territory before carrying out the assault. About 100 people were killed and 40,000 displaced in the attack in the Catatumbo region.
The National Liberation Army (ELN), the world's oldest active guerrilla group, launched the attack last week, targeting a rival faction and civilians. According to the report, at least 80 combatants armed with assault rifles and explosives moved through Venezuela's border states of Táchira and Zulia before crossing into Colombia.
