Colombia's peace tribunal ordered the arrest of four rebel leaders who appeared in a video Thursday pledging to resume their insurgency.
A tribunal statement said that Luciano Marín, the former chief negotiator for the Revolutionary Armed Forces of Colombia, and top allies who appeared alongside him while heavily armed immediately lost their benefits under the 2016 peace deal on ending a half-century of bloody fighting.
Under terms of the accord, rebels who confess their war crimes and compensate victims are spared jail sentences and protected from extradition to the U.S.

The day's top national and international news.
Earlier Thursday, Colombian President Ivan Duque offered a nearly $1 million reward for Marín's arrest of after the rebel and a small cadre of hardliners vowed to resume their insurgency in a major reversal for the country's efforts to end decades of bloody fighting.
In a televised address, Duque also accused Venezuela's socialist leadership of providing safe haven to the rebels — underscoring the risks to regional stability from the rebels' shock announcement they would rearm.
In a video published after midnight Thursday, Luciano Marín appeared alongside some 20 heavily armed insurgents dressed in camouflaged fatigues condemning the conservative Duque for standing by as hundreds of leftist activists and rebels have been killed since demobilizing as part of the peace deal.
"When we signed the accord in Havana we did so with the conviction that it was possible to change the life of the most humble and dispossessed," said Marín, better known by his alias Iván Márquez, in the more than 30 minute video. "But the state hasn't fulfilled its most important obligation, which is to guarantee the life of its citizens."
Marín read the lengthy prepared remarks from what looked like an established guerrilla camp in what he said was Colombia's eastern jungles.
But Colombian authorities swiftly alleged the video was shot in neighboring Venezuela — long a strategic rearguard for the rebels and whose socialist government the Trump administration and several conservative U.S. allies, especially Duque, have been seeking to remove.
"We're not witnessing the birth of a new guerrilla army, but rather the criminal threats of a band of narcoterrorists who have the protection and support of Nicolás Maduro's dictatorship," Duque said. "We won't fall into the trap of those pretending to shield themselves behind false ideological clothing to sustain their criminal structure."
The decision to return to arms was overwhelmingly rejected by Colombians, many of whom believe the rebels benefited from a sweetheart pact of impunity. It comes as the peace process is at risk of unraveling because of what critics see as its slow implementation and a surge in killings of social leaders in far-flung rural areas where the rebels had long been dominant.
With two pistols strapped to his belt, Marín pledged a "new phase" in Colombia's armed conflict and vowed to seek alliances with another rebel group, the National Liberation Army, or ELN. Standing alongside him were several former FARC leaders, including ideologue Seuxis Hernández, alias Jesús Santrich, who abandoned the peace process after prosecutors in New York ordered his arrest on drug charges.
Maduro last month said the fugitive rebel leaders would be welcome in his nation and for months, Colombian military intelligence have alleged that that Marin, Hernández and several top ELN commanders were hiding out in the neighboring country.
Patricia Linares, head of the special peace tribunal investigating the FARC's crimes, indicated that magistrates would move quickly to strip the deserting rebels of benefits under the peace deal. Under the accord, rebels who confess their involvement in war crimes like the kidnappings of civilians and recruitment of child soldiers will be spared jail time and protected from extradition to the U.S., which has charged the FARC's top leadership with cocaine trafficking.
"Whoever rearms will be expelled," Linares said.
It's unclear how the decision by Marín to rearm will affect Colombia's delicate security balance. More than 90% of the 13,060 ex-combatants and civilian supporters who handed over weapons to United Nations observers in 2016 continue to live up to their commitments under the peace deal.
But a group of dissident FARC commanders never demobilized and have seen their ranks swell to around 2,500 fighters through recruitment. They continue to terrorize isolated rural communities, especially along Colombia's borders with Venezuela and Ecuador, profiting from a booming cocaine trade in those areas.
In addition, the more radical ELN has filled the void left by withdrawing FARC rebels and stepped up attacks in cities, including the car bombing of a police academy in Bogota that killed 22 people.
Marín's move is "better late than never," said an ELN commander in Colombia's western jungle who goes by the alias Uriel. The fighter released a video on social media in which he appeared along a river with his face masked and fist clenched in the air.
Rodrigo Londoño, who had been the FARC's top military commander and now heads its legal political party, immediately distanced himself from his former comrades, with whom relations have been strained in the past year. In an interview with Blu Radio he apologized to his fellow Colombians and the international community, saying that the vast majority of rebels remain committed to the peace process despite rising security risks.
"I have mixed feelings," said Londoño, who is better known by his alias Timochenko. "It's an unfortunate development, but at the same time it leaves things clearer and ends the ambiguity because we had been facing a complex situation for some time."
Duque's peace commissioner, Miguel Ceballos, called for swift action from the peace tribunal while calling on prosecutors to seek the rebel leaders' arrest. At a press conference in Washington, he also lashed out at what he said was "clear support by the dictator Nicolás Maduro" for the rebels.
Duque rose to power last year on a law and order platform opposing many aspects of the peace deal. But in office, he's moderated his views and started implementing ambitious aspects of the accord to build roads, schools and other infrastructure in traditionally neglected areas of the country where the state's presence has historically been limited.
But critics, including the architects of the peace deal, have accused him of not doing enough to protect leftist activists and aligning with the U.S. to gut the special peace tribunals whose goal is to foster reconciliation and truth-telling for victims instead of seek full punishment for war atrocities.
"90% of the FARC remain in the peace process. We must continue to fulfill our obligations to them, and repress the deserters with complete force," former President Juan Manuel Santos, who was awarded the Nobel Peace Prize for his efforts to end the nation's armed conflict , said in a message on Twitter. "The battle for peace must not stop!"
