Pope Francis holds hands with children wearing traditional costumes as he walks with Bolivian President Evo Morales upon his arrival at the El Alto airport, Bolivia, Wednesday, July 8, 2015. The pouch Francis is wearing around his neck was given to him by Morales. It's woven of alpaca with indigenous trimmings and traditionally used by people in the Andes to hold coca leaves, which they chew to ward off the ill effects of extreme altitude. Due to the altitude, the pope will spend only a few hours in the capital city La Paz, during his South American tour. Bolivia is the second of three countries Francis will be visiting on his South American tour. (AP Photo/Gregorio Borgia)
