Colombia’s President Ivan Duque said five Indigenous people were killed and six injured by narco-trafficking groups in the country’s southwest.

Those responsible for the deaths in Cauca province are drug trafficking groups that wanted to maintain business, Duque said on Wednesday in a video statement on Twitter.

“We join the pain of communities and families,” he added.

The Regional Indigenous Council of Cauca (CRIC) denounced the murder of indigenous leader, Cristina Bautista, and four volunteer guards of the Tacueyo community.
