to avoid being defeated. They planned to intensify guerrilla warfare by the use of landmines, snipers, and bomb attacks in urban areas. They also plan to buy missiles to fight the Colombian airforce which highly contribute to their weakness since few years. In February 2009, the guerrilla released 6 hostages as a humanitarian gesture. In March, they released Swedish hostage Erik Roland Larsson. In April 2009, the Colombian armed forces launched Strategic Leap, an offensive in border areas where the FARC's forces still has a strong military presence, especially in Arauca, near the Venezuelan border. In November 2009, Nine Colombian soldiers were killed when their post was attacked by FARC guerrillas in a southwestern part of the country. On December 22, 2009, FARC rebels raided the home of Provincial governor Luis Francisco Cuéllar, killing one police officer and wounding two. Cuellar was found dead the following day. 2010–2016 On January 1, 2010, Eighteen FARC rebels were killed when the Colombian Air Force bombed a jungle camp in Southern Colombia.
