Colombia forces scored what President Santos called an historic blow against the FARC with the killing of top leader Guillermo Leon Saenz, better known by his nom de guerre Alfonso Cano, on Nov. 4, 2011. Colombia’s forces bombed a hideout in a jungle in the southwestern province of Cauca, later rappelling down in helicopters to find Mr. Cano.
He was killed in a gun battle, officials say.
Cano joined the FARC in 1982, and in 1984 became part of the group’s seven-man leadership. He took over the head of the FARC in 2008 after the death of Manuel "Sureshot" Marulanda.
"It is the most devastating blow that this group has suffered in its history," Santos told the nation on TV.
