Pope Francis prays in front of an image of Our Lady of Chiquinquira which was installed for his visit upon his request, at 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
