“This is hell,” says Gabriela, a Venezuelan refugee working as a prostitute in the Colombian border town of Cucuta.

The 19-year-old traveled 22 hours from La Guaira in Venezuela to work in Cucuta. Gabriela was not unaware of the job awaiting her. Like many others working in the sex industry in Cucuta, she’d heard about the opportunity from others who had already made the perilous journey across the border, reports Voice of America.
