>> When President Juan Manuel Santos and leaders of the Revolutionary Armed Forces of Columbia, or FARC, shook hands to end a half century war, many Colombians were relived. But nearly two years later peace still remains elusive in this country of 50 million people. Which even today, is the worlds largest producer of cocaine.
Reuters senior correspondent Helen Murphy is in Santander, Colombia.>> So what's basically happened is, as the FARC have moved out of much of these areas dissident FARC who didn't want to join the peace accord. Paramilitary groups, right wing paramilitary groups, new crime gangs are setting up new guerilla movements to try and continue with the drug trafficking that the FARC were involved with.
The strongest of the many armed groups emerged from FARC's shadow is the National Liberation Army, or ELN, an anti-capitalist guerilla group responsible for bombings across Colombia.>>
> Anyone who is ready to fight with a rifle or otherwise, who identifies with us as a comrade, and who wants to build a more just and equitable Colombia is welcome.
>> But some say the gangs have little ideology beyond crime. And are spawning blood shed across Columbia as they vie for control.>> It's causing an awful lot of problems for cities and areas like Tumaco where the murder rate has soared. There's a lot of people getting killed all the time, and the government basically having a difficult time to contain that.
>> The region around Tumaco is where the most cocoa leaves are grown. Farmers are happy to grow the crop for the lucrative payoff even as the drug trade there has become more dangerous. Tumaco's resident say that when FARC controlled local drug routes they ensured the safety of people in the towns.
But as the new armed groups fight for control, everyone in their path is vulnerable. Columbia's government says it is doing all it can to restore law and order. And has already deployed 80,000 police and soldiers to suppress the groups that are putting a fragile Columbia's future in jeopardy.
