On Wednesday, Colombia sent a new unit of 14,000 military soldiers to bolster government control of a conflict hotspot near the Venezuelan border, where several armed groups vie for control of cocaine manufacturing.

The new CENOR unit, which is stationed in the northeastern region of Norte de Santander, is Colombia’s largest in recent history.

President Ivan Duque said the unit’s mission would be to combat drug trafficking, terrorism, and organized crime funding during a ceremony marking the unit’s launch on Wednesday.

CENOR will confront dissident members of the demobilized FARC rebels who reject a 2016 peace deal, guerrillas from the National Liberation Army (ELN), and criminal groups including the Clan del Gulfo, which compete to control crops of coca, the chief ingredient of cocaine.

The province is one of Colombia’s most dangerous, with several high-profile assaults recently.

FARC insurgents exploded a vehicle bomb near Cucuta’s military camp in June, wounding scores. Shots were fired at a chopper transporting Duque later that month.

According to the government, the deployment would be accompanied by investments to combat poverty and substitution and eradication initiatives to eliminate illicit crops.

Colombia’s almost six-decade-long armed war has resulted in the deaths of over 260,000 people and the displacement of millions.

The Andean country has long accused neighboring Venezuela of sheltering illegal armed groups and allowing drug trafficking to take place in exchange for a cut of the profits. Venezuela’s President Nicolas Maduro has denied the accusations.

“We need to make sure there is no collusion – like we have seen on the part of the Venezuelan dictatorship – in the border region to sponsor drug trafficking and other international crime,” Duque said.
