It's less than three years since a historic peace deal ended a 52-year war between the Colombian state and Farc guerrillas. Over 200,000 people were killed in that war and 7 million more were displaced. Today, the peace process is still taking root. But two weeks ago on August 29th, Colombians were shocked to see a video message from the jungle appearing on YouTube, featuring several former Farc commanders dressed in camouflage and brandishing assault rifles.

In the video, the former FARC commanders Ivan Marquez and Jesus Santrich accuse the government of not living up to its commitments under the peace deal and declare their return to arms.

To talk about the threat posed by dissidents to the peace process, the peace deal’s difficult implementation, deputy foreign editor David McKechnie interviewed Emilio Archila, Presidential Counsellor for Stabilisation in Colombia, and one of the key people in charge of implementing the peace deal.
