Arizona Tribune - Colombia vows 'war' as guerrilla violence kills 100

In just five days, violence has been reported in three different Colombian departments -- from the remote Amazon jungle to the rugged border with Venezuela, where fighting has displaced 11,000 people.

President Gustavo Petro, who until now has staked his political fortunes on a strategy of negotiations and engagement, signalled a much tougher approach in the face of the mounting crisis.

On Monday he issued a defiant warning to leaders of the National Liberation Army -- or ELN -- which is said to have been behind border region attacks on rival leftist groups, killing 80 people.

The ELN, Petro said, had "chosen the path of war, and war they will have".

Some 5,000 troops are already being sent to the border area, hoping to contain some of the worst violence Colombia has seen in years.

The country is plagued by an abundance of leftwing, rightwing and apolitical armed groups and cartels that vie for control of the lucrative cocaine trade.

The Ombudsman's Office reported ELN rebels going from "house to house," killing people suspected of ties to the FARC dissidents.

Over the weekend, terrified residents carrying backpacks and belongings on overladen motorcycles, boats, or crammed onto the backs of open trucks, fled the region.

Hundreds found refuge in the town of Tibu, where several shelters were set up, while others crossed the border to Venezuela -- for some a return to a country from where they had fled economic and political upheaval.

"As a Colombian, it is painful for me to leave my country," Geovanny Valero, a 45-year-old farmer who fled to Venezuela, told AFP, saying he hopes the situation will be "sorted out" so he can return.

On Monday, Colombia's defense ministry reported new clashes in a remote Amazon region.

A ministry official told AFP that 20 people had been killed in fighting between rival left-wing guerrillas in the jungle-clad department of Guaviare.

The Amazon clashes involved rival FARC splinter groups -- leftwing guerrillas who, unlike the rump Revolutionary Armed Forces of Colombia, have not signed peace accords.

The clashes are a fresh challenge for Petro who has backed a policy of "total peace."

In the face of some public opposition, he launched negotiations with the various hardline armed groups that still control parts of Colombia after being elected in 2022.

Critics allege that his conciliatory approach has emboldened groups who are often funded by the proceeds of cocaine and other trafficking and allowed them space to grow in power and influence.

A 2016 peace deal with FARC was hailed as a turning point in the six-decade-long conflict between Colombian security forces, guerrillas, right-wing paramilitaries and drug gangs, which has left nearly half a million people dead.

But dissident factions continue to control territory in several parts of Colombia, the world's biggest cocaine producer.
