Colombian President Juan Manuel Santos, left, reads aloud words engraved on a pen as he meets with Pope Francis at the Vatican, Friday, December 16. The words "The bullets have written our past, education will write our future" are engraved on the pen, made from a recycled bullet once used in the civil war between the Colombian government and the Revolutionary Armed Forces of Colombia (FARC). The pen was later used to sign the peace agreements between the parties earlier this year. Santos, who was awarded the 2016 Nobel Peace Prize for his efforts to end the region's longest-running conflict, presented Pope Francis with the pen.
