The Trump administration has allegedly begun deporting individuals from Myanmar and Vietnam to South Sudan, despite a federal court order restricting such transfers, according to court filings from immigration attorneys.

A federal judge ruled late Tuesday that U.S. officials must retain custody and control of migrants apparently removed to South Sudan in case he orders their removals were unlawful.

Lawyers for the immigrants, who aren’t from South Sudan, contend the deportations violate a court order after a previous attempt to send some people to Libya.

A federal district court judge in Boston ruled on Wednesday that the Trump administration’s attempt to send several immigrants from other countries to South Sudan violated a court order blocking the government from deporting people to third countries without allowing them to object to their removal.

The foreign men convicted of crimes who were placed on a deportation flight headed for the chaotic nation of South Sudan were originally from countries as far away as Mexico and Vietnam. They had lived in various places from California to Iowa, Nebraska to Florida, with one serving a sentence of nearly 30 years.
