Colombia’s president has issued a decree giving him emergency powers to restore order in a coca-growing region bordering Venezuela that has been wracked in recent days by a deadly turf war among dissident rebel groups.

The Colombian border village of Tres Bocas has become a ghost town as residents flee to neighboring Venezuela to escape a new wave of violence that has left at least 80 people dead and displaced thousands in Colombia’s Catatumbo region.

Both the ELN and FARC-EMC have long fought for control over this drug-rich area, but recent violence marks a significant escalation.
