BOGOTA (Reuters) - Colombia's FARC rebel group said its 3-month-old unilateral ceasefire, declared amid peace talks with the government to end 51 years of war, may be at risk because of a rise in military actions against its fighters.

The Revolutionary Armed Forces of Colombia, or FARC, who have been negotiating with the government for three years, said in a statement that continued military operations like one last week that killed four rebels threaten to make the unilateral ceasefire unsustainable.
