A former commander of Colombia's Farc rebel group, Iván Márquez, has released a video six months after hiding.
In the film, he accuses the government of betraying the terms of the historic peace agreement signed in 201
He says 400 community leaders and 85 former warriors have been killed since the peace agreement was signed.
Márquez led Farc's negotiating team in the negotiations, which was held in Cuba and lasted four years.
Farc always said that it feared reprisals from those who opposed the peace process.
In April, one of his most senior leaders, Jesús Santrich, was arrested at the request of the United States accused of drug trafficking.
Soon after, Márquez resigned from his seat in the Colombian Senate and hid.
Márquez does not reveal his whereabouts during the 12-minute video he was preparing for the 24th international Rosa Luxemburg conference in Berlin.
Colombia's Farc or Revolutionary Defense Forces is now a political party called the Revolutionary Alternative Joint Force with five seats in the Senate and five in the House of Representatives.
& # 39; Results are discouraging & nbsp;
Marquez said that leftist group had made a decisive mistake during the final stage of the debate: "We agreed to put our weapons before we secured an agreement on the political, economic and social integration of the struggle."
But the former commander, whose real name is Luciano Marín, said he was determined to peace and full implementation of the agreement.
"On November 24, 2016, Havana signed the final agreement to end the conflict and create stable and lasting peace," he said.
"Only two years later, the results of government implementation are abominable."
President Iván Duque's government says it is taking steps to increase secrecy for former rebels.
Duque, a vocal critic of the peace agreement, joined in August.
He replaced Juan Manuel Santos, who won the Nobel Peace Prize for his role in the deal with Farc, which put an end to more than five decades of conflict.
A week ago, United Nations President António Guterres called on President Duque to do more to protect former rebels.
He said many of them had been killed by illegal armed groups and drug addicts.
