Colombia's Marxist FARC rebels accused the government Sunday, June 4 of "repeatedly breaking" terms of their peace deal, and threatened to delay their demobilization, AFP reports.
"After the government's repeated non-compliance with the Peace Agreement (signed in November), the FARC is going to seek international monitoring," rebel leader Rodrigo Londono, AKA Timochenko, warned on Twitter.
Timochenko earlier said he was "considering" postponing demobilization.
It was not immediately clear what the FARC rebel leader meant about international oversight, which is already part of the UN-monitored peace process even after demobilization.
Earlier, President Juan Manuel Santos said the government said would stick to its calendar. "That is our commmitment and we will fulfill it," he said. The president has called the peace process "irreversible."
The peace deal aims to end Latin America's longest-running civil war which has dragged on more than five decades.
Several incidents have been mentioned by the FARC as serious, including FARC doctor Jose Vasquez being detained Sunday at a roadblock in San Jose del Guaviare.
The government and the FARC, formally known as the Revolutionary Armed Forces of Colombia and the country's biggest rebel group, reached a deal after four years of negotiations in the Cuban capital.
Colombian voters rejected it by a narrow margin in a referendum in October.
Santos and FARC leaders then drafted a new version of the accord and the government pushed it through Congress despite resistance from critics.
