Colombia's two guerilla groups that remain in arms pledged this week to open a dialogue with each other to bring their internecine conflict to an end. Fighting broke out weeks ago between the National Liberation Army (ELN) and its smaller rival, the Popular Revolutionary Army (EPL) in the northeastern Catatumbo region. William Villamizar, governor of Norte de Santander department, has declared a state of emergency over the violence, which he said has displaced some 1,000 families. The fighting is said to have begun as the two groups vied to take control of coca-growing lands vacated by the demobilized FARC guerillas.
