Pope Francis prays during a visit to the Cathedral of 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 / Alberto PIZZOLI
