Fighting between two rebel groups in Colombia has caused the governor of one remote province to declare a state of emergency. The EPL and the ELN are fighting for control of a coca-growing region. The fighting is greatly affecting civilians in the region. William Villamizar, governor of Norte de Santander, said the emergency declaration was necessary to assist people displaced by the clashes. According to him, about 1,000 families had fled the fighting and 4,000 children were unable to go to school. Much of this regions used to be under the control of the Farc rebels. But since signing a peace deal with the government they have since left a power vacuum in the area.
