Adrian Naveda (C) and Natacha Rodriguez, who are traveling by bus from Caracas to Chile, sleep sitting on the floor while they wait in line to have their passport stamped at the binational border service centre in Huaquillas, Ecuador, November 11, 2017. After four days of traveling, the fatigue among the passengers was evident. Having boarded the last bus in Guayaquil after midnight and travelled approximately four hours to the border between Ecuador and Peru, many fell asleep on the floor while queuing to get their passports stamped.
