In the United States, legal groups including the ACLU of Washington are suing Immigration and Customs Enforcement to block them from retaliating against immigrant hunger strikers at the Northwest Detention Center in Washington state. Activists say 20 hunger strikers and supporters have been placed in solitary confinement at the prison, which is run by the for-profit GEO Group. At one point last month, at least 750 prisoners were on hunger strike demanding better conditions and an end to record deportations.
