On his personal blog, Colombian journalist Javier Contreras wonders [es] if there really was a ceasefire during the Christmas and New Year truce between the Guerrilla group FARC [es] and Colombian government, in the context of peace negotiations ongoing since late 2012:

According to figures from the Ombudsman Office, during the month-long unilateral truce granted by the Farc amidst the peace negotiations with [President] Santos administration, there were 57 terrorist attacks.

So, things have to be told just as they are: there was no truce. If there were nearly two terrorist attacks per day during that period, there was no real cease of actions against public force or civil population; this was really a ploy to Colombians and a demonstration that believing the Farc, even during the Havana negotiations, generates a lot of scepticism.
