The FARC and the smaller National Liberation Army (Ejército de Liberación Nacional, ELN) committed serious human rights abuses and violations of international humanitarian law, including unlawful killings, hostage-taking and the recruitment of children.
The FARC in particular carried out indiscriminate attacks in which civilians were put at risk through the use of low-precision explosive devices.
According to government figures, 35 members of the security forces and one civilian were killed in 2010 and 363 injured by anti-personnel mines employed predominantly by the FARC.
According to government figures, there were 282 kidnappings in 2010, compared with 213 in 2009. Most were attributed to criminal gangs, but guerrilla groups were responsible for most conflict-related kidnappings. However, the main NGO supporting victims of kidnapping, País Libre, criticized the government agency responsible for compiling kidnapping statistics, Fondelibertad, for claiming that only 79 people remained in captivity as of February.
