Negotiators from the Colombian government and the country's biggest guerrilla army have resumed peace talks in Havana after the rebels briefly walked away from the table last week. According to AP, the two sides are still in disagreement on the issue behind the time-out: whether to call an assembly to rewrite the constitution if a peace deal is reached. Still, the FARC said Monday that it would remain in the talks, "faithful to the commitment to seek peace for Colombia through all means."
