The Colombian government and the Farc rebels have signed a historic ceasefire deal, bringing them closer to ending more than five decades of conflict. The announcement was made in Cuba by Colombia’s President, Juan Manuel Santos, and Farc leader Timochenko. The ceasefire is expected to pave the way for a full peace deal. The longest-running insurgency in the Western Hemisphere has killed an estimated 220,000 people and displaced almost seven million. Thursday’s announcement caps formal peace talks that started three years ago in the Cuban capital Havana. The agreement includes a timetable for laying down arms and a number of guarantees for the security of the guerrillas when they disarm.
