The FARC, or Revolutionary Armed Forces of Colombia, declared the ceasefire when the talks began on November 19 in Havana, and gave the Colombian government two months to also lay down its arms. The fact is that the number of operations carried out by the group decreased significantly, the number of police and soldiers killed or injured decreased ... The conclusion is that there was a relative compliance with the ceasefire," Colombian President Juan Manuel Santos said late on Sunday. Santos said the FARC was involved in some violence during the ceasefire, but it was hard to tell whether the guerrillas were defending themselves or attacking. Santos, who had rejected the ceasefire from the beginning, said the rebels may be planning a new offensive. Marquez did not disclose their plans, but urged Santos to reconsider the government's decision not to lay down arms. Colombian officials had called the ceasefire a sham to gain international favor and said the government would maintain the military pressure to keep FARC at the negotiating table. Santos also said the government's armed forces had captured three members of the National Liberation Army, Colombia's second largest guerrilla movement, who were involved in the kidnapping on Friday of five mining company workers. The group, including a Canadian, two Peruvians and two Colombians worked for the Canadian mining company Braeval at a gold mine project. "We know the area in which they are, but we'll be careful to protect the lives of these people," Santos said.
