In a statement released late Thursday, the Ecuadorean Foreign Ministry said the guarantor nations - including Brazil, Chile, Cuba, Venezuela and Norway - attested that "the two parties have expressed their willingness to overcome this moment and continue the conversations conducive to peace". The negotiating teams are in Quito, Ecuador, which is hosting the talks. The government said that the rebels attacked the pipeline with three bombs.
From the beginning, the Colombian government was skeptical of whether or not ELN leaders could ensure compliance among their ranks if a peace deal were in fact achieved.
State oil company Ecopetrol had earlier reported a "possible attack" on a well in the eastern department of Casanare.
"The National government", Santos continued, "was always ready to extend ceasefire with that organization and negotiate a new one". The dialogues have been rocky from the get-go, and InSight Crime's research suggests that the ELN have been in expansion mode despite their calls for an end to the conflict.
The attacks threaten future negotiations for peace but the negotiator of the group said the attacks happened in complex situations of war. The first attack left two soldiers injured. The rebels also accused the government of failing to live up to their end of the accord during the 101-day ceasefire. "If there's a positive response, the ELN delegation will remain in Quito", Beltran said.
The members of the Security Council echoed the Secretary-General's concern about increased insecurity in some of the areas affected by the conflict, welcomed the important efforts by the Government of Colombia to address these concerns, as well as steps to address other issues including access to land, and looked forward to their swift implementation. The government in turn vowed to improve conditions for jailed rebels as well as boost protections for leftist activists in areas dominated by the ELN. They recently relaunched as a political party and plan to run in this year's presidential election.
