Colombia's ELN guerrilla group used drones and explosives in Thursday night attack that also injured at least 30 soldiers

Colombia's ELN guerrilla group has attacked a military base near Venezuela with drones and explosives, killing seven soldiers and wounding 30.

Founded in 1964 and inspired by the Cuban revolution, the ELN is the oldest surviving guerrilla group in the Americas, and controls key drug-producing regions of Colombia. Efforts to negotiate a peace settlement have repeatedly stalled.
