A nun walks by as people demonstrate against the visit of Pope Francis to Chile, in the surroundings of O'Higgins Park in Santiago on January 16, 2018 where the pontiff is scheduled to give an open-air mass. The pope landed in Santiago late Monday on his first visit to Chile since becoming pope, and his sixth to Latin America - a trip that will also take him to Peru. / AFP PHOTO / EITAN ABRAMOVICH
