An Afro-Colombian woman holds a sign that reads: 'Let war stop, not peace' during the Peace Day in Cali, Colombia, on April 9, 2015. The Colombian government is negotiating with the Marxist-inspired Revolutionary Armed Forces of Colombia (FARC) to end decades of bloody war which has killed around 220,000 people and uprooted more than five million since the FARC launched its rebellion in 1964.
