Two days after the Revolutionary Armed Forces of Colombia broke a unilateral ceasefire, ambushing and killing 11 soldiers in rural Cauca province, Santos pledged to remain at the negotiating table with the rebels but called for a timeline.
"Do not be deaf to Colombians who are shouting for an end to the war, who are losing patience," Santos said in a televised address.
"We must put deadlines on this process and if (the FARC) want peace they must demonstrate with deeds and not with words."
