Shortly after the government of Colombia refused to give in to the FARC guerillas' original demands for a humanitarian exchange, the FARC released the last of their political hostages.
The FARC guerrillas originally demanded that in order to proceed with the humanitarian exchange, the government must demilitarize a zone, which are the municipalities of Pradera and Florida in the southern Department of Valle del Cauca. The government of Colombia maintained that this is impossible and non-negotiable. The FARC guerrillas eventually dropped their prisoner exchange demand and released their last political hostages in April 2012. However, after Ingrid Betancourt and three American contractors were rescued in July 2008, the FARC dropped that demand because they no longer had their most famous bargaining chips.
