2010 Colombia–Venezuela diplomatic crisis

The 2010 Colombia–Venezuela diplomatic crisis was a diplomatic stand-off between Colombia and Venezuela over allegations in July by Colombian President Álvaro Uribe that the Venezuelan government was actively permitting the FARC and ELN guerrillas to seek safe haven in its territory. The Revolutionary Armed Forces of Colombia (FARC), founded in 1964, is the largest of Colombia's left-wing guerilla groups, and the National Liberation Army (ELN), also founded in 1964, is another left-wing guerilla group inspired by the Cuban Revolution (1953–1959) and Marxist ideology.
