Colombian police help Colombian citizens carry their belongings as they cross the Tachira border river from Brisas de Barinitas, Tachira state, Venezuela to Colombia on August 25, 2015. Colombia complained Monday that Venezuela's mass deportation of its citizens during a crackdown on smuggling has created a "humanitarian tragedy" on part of their border.
