Cauca

The incident in the southern Cauca region highlights the ongoing violence in the South American country.

The battle occurred in the dense rainforests of Valle del Cauca, western Colombia.

Indigenous leaders in the war-torn western region of Cauca said an attack by the dissident group Saturday wounded at least three people and a young student was taken away by force.

"We want to make the first concerted effort to swap one economy with another, with the whole community," Petro, a leftist, said during an event in El Tambo, a municipality in Cauca province, and one of the regions most affected by coca crops.

An initial series of talks took place on Sunday in Colombia's southwestern Cauca region, with delegates from the European Union, United Nations and Organisation of American States in attendance.
