In the aftermath of the closure of the Colombia-Venezuela border, criminal groups have seized control of illegal trails, known as "trochas," that have become the only transit option for citizens moving between the two countries.
As the biggest irregular army in Colombia, the Revolutionary Armed Forces of Colombia (Fuerzas Armadas Revolucionarias de Colombia - FARC) have long operated in various regions of the country in search of resources to fund their insurgency. They agreed to end their 52-year war against the government in August 2016, as part of a peace process that began in 2012.
The FARC are the oldest and most important guerrilla group in the Western Hemisphere. They have long financed their political and military battle against the Colombian government through kidnapping, extortion and participating in the drug trade on various levels.
