( CNN ) -- An operation to retrieve two Colombian hostages held by the FARC rebel group will resume Tuesday , the Red Cross said , but the government denied that it had authorized such a move . The conflicting reports come two days after an initial attempt to retrieve the hostages was foiled by inaccurate coordinates . Christophe Beney , the Red Cross representative for the operation , said that the release of police Maj. Guillermo Solorzano and Army Cpl . Salin Sanmiguel by the Revolutionary Armed Forces of Colombia or FARC will happen in the department of Cauca on Tuesday morning . But shortly after these comments were reported , the Colombian government said in a statement that `` it is not true that we have authorized the resumption of any operation for the liberation of the hostages . '' The government was awaiting a debrief from the Red Cross before moving forward , the statement said . Solorzano , Sanmiguel , and police officer Carlos Ocampo were to be released by the FARC on Sunday , but only Ocampo was freed . Colombian authorities were upset at what they said were wrong coordinates given by the Marxist guerrilla group . `` Even though the government did its part , the FARC have committed an act that shocks us , '' said Eduardo Pizarro , the government 's representative for the liberation operation . `` Today , the FARC gave us coordinates in the department of Tolima . The helicopters went to those areas , and it turns out that the hostages are n't in the department of Tolima , but in the department of Cauca . '' He added that `` this behavior surprises , upsets and disturbs us very much . '' In December , the FARC leftist guerrilla group pledged to release five hostages as a humanitarian gesture . Three of them were released last week , and two others had originally been scheduled to be released Sunday . However , former Sen. Piedad Cordoba , who helped to coordinate the humanitarian mission , later said that the rebel group would release three hostages Sunday . Some have suggested the hostage releases could fuel renewed negotiations between Colombia 's government and the rebels . One of the freed hostages called for dialogue between the government and insurgents . `` Humanitarian exchange is the first step toward a friendly understanding , which permits the return of our brothers deprived of their liberty , '' politician Armando Acuna said after his release last week . But Colombian President Juan Manuel Santos has sharply criticized the FARC , accusing the group of having a `` double standard '' and creating an `` absurd media show '' in order to draw sympathy to their cause . On Thursday , he said he was tempted to call off the rescue mission after learning that two workers from the Carton de Colombia company had been kidnapped in southwestern Colombia on Wednesday night . Journalist Fernando Ramos contributed to this report .
Red Cross says it is ready to resume a liberation operation , . But the government says it has not signed off on such a move . Two hostages who were to be released Sunday were not released . The government was upset that it was given wrong coordinates .
