Bogota/Havana, Muharram 03, 1438, October 04, 2016, SPA -- The Colombian government and FARC guerrilla group began work Monday to try to salvage their peace accord in the wake of a surprise defeat for the deal at the polls, according to dpa. President Juan Manuel Santos met with nearly all of Colombia's political parties at the presidential palace in Bogota, to open a national dialogue on the peace process in the wake of the vote Sunday, in which a razor-thin majority of Colombians rejected the accords. Senate President Mauricio Lizcano said after the meeting that those who took part in the meeting supported the president in an attempt to salvage the peace process through renewed dialogue with a "specific timeline and concrete results." But former president Alvaro Uribe and his far-right Democratic Centre party who led opposition to the deal, did not join Monday's talks. Instead, the party issued a statement saying that it was ready for dialogue and asking the country to take note of its "reasons" for the no vote. Uribe and other opponents say they support the peace process but believe the accord finalized August 24 and signed in a ceremony in Cartagena a week ago was not tough enough on the Revolutionary Armed Forces of Colombia (FARC) guerrilla group. The deal would have allowed FARC leaders to serve in Congress, with a guarantee of 10 seats, and serve reduced sentences for crimes committed during the 52-year armed conflict - concessions opponents say went too far. FARC leader Rodrigo "Timochenko" Londono said the deal remained in effect despite Sunday's popular vote rejecting it. "The [vote] does not have any legal effect. The effect is political," he said on Colombian television. FARC said Monday that a bilateral ceasefire agreed in August would stand, echoing Santos' promise Sunday to maintain the peace while both sides searched for a way forward. The defeat of the 297-page peace accord by a margin of less that a quarter of a percentage point came as a shock after observers had predicted a clear win, and left the government and FARC scrambling for a way to salvage the deal. Santos said he was sending two top negotiators back to Havana, site of the nearly four years of peace talks, to meet with FARC - even though one of them, lead negotiator Humberto de la Calle, had offered his resignation. UN Secretary General Ban Ki-moon also sent a special envoy, Jean Arnault, to Havana to join them. World leaders rallied around the peace process, which had up to Sunday's vote been seen as a favourite for the Nobel Peace Prize. European Union foreign policy chief Federica Mogherini said Europe respected the "sovereign choice" of the Colombian people, and would continue to support all steps toward securing a permanent end to violence. "It is now for all sides in Colombia to unite and find the path that can lead the country to peace," she said in a statement. White House spokesperson Josh Earnest said the White House was hopeful the parties "can settle on a path that leads to the kind of negotiated settlement and negotiated peace that all of the parties have indicated they would like to see." He said the US stood ready to send an envoy to talks. The peace accord between Colombia and the FARC was intended to put an end to 52 years of armed conflict that have killed 220,000 people and displaced millions. --SPA 02:35 LOCAL TIME 23:35 GMT www.spa.gov.sa/w
