Colombia peace agreement

Updated at 6:13 p.m. ET Friday

Top rebels from the Revolutionary Armed Forces of Colombia have announced a "new stage of fighting," despite a peace accord that the leftist guerrilla group signed with the national government almost three years ago.

In a 32-minute YouTube video posted Thursday, more than 20 armed fighters stood in green fatigues and in front of a sign that read, "As long as there is a will to fight there will be hope for victory."

Last fall Colombia was being called “the Brexit of the Americas.” That’s because, in stunning Brexit fashion, voters there had just rejected a peace agreement to end the country’s half-century-long civil war. Most Colombians felt the accord was too lenient toward the Marxist guerrillas known as the FARC.
