Pope Francis (L), accompanied by the Archbishop of Bogota Cardinal Jesus Ruben Salazar, waves from a balcony of the Archbishop's Palace at people gathering at Bolivar Square in Bogota on September 7, 2017. Pope Francis urged Colombians to avoid seeking "vengeance" for the sufferings of their country's half-century civil conflict as they work towards a lasting peace. The 80-year-old pontiff spoke alongside Colombia's President Juan Manuel Santos, who has overseen recent controversial efforts to make peace with armed rebel groups. / AFP PHOTO / Luis ROBAYO
