Over 80 people have died and tens of thousands have been displaced in escalating violence between armed groups as the border city of Cucuta scrambled Wednesday to cope with thousands of civilians fleeing the violence.

The unusually deadly violence delivers a devastating blow to the “total peace” program of the country’s first leftist president, Gustavo Petro.

Colombian President Gustavo Petro said Monday he will declare a state of emergency after guerilla attacks by the ELN in the northeast of the country killed at least 80 people and forced over 11,000 to flee.
