US Department of State: Trafficking in Persons Report 2016 - Bahrain section
Bahrain is a destination country for men and women subjected to forced labor and sex trafficking. Men and women from South, Central, Southeast, and East Asia; East and West Africa; the Middle East; and other countries migrate voluntarily to Bahrain to work as domestic workers or as laborers in the construction and service industries. In recent years, NGOs observed a greater influx of workers from parts of Africa. Some migrant workers face forced labor after arriving in Bahrain, experiencing unlawful withholding of passports, restrictions on movement, contract substitution, non-payment of wages, threats, and physical or sexual abuse.
