El Salvador, Venezuela, Rwanda, now Libya.
From NYTimes:
The Trump administration is planning to transport a group of immigrants to Libya on a U.S. military plane, according to U.S. officials, another sharp escalation in a deportation program that has sparked widespread legal challenges and intense political debate.
The nationalities of the migrants were not immediately clear, but a flight to Libya carrying the deportees could leave as soon as Wednesday, according to the officials, who spoke on the condition of anonymity because they were not authorized to discuss the operation.
The decision to send deportees to Libya was striking. The country is racked with conflict, and human rights groups have called conditions in its network of migrant detention centers “horrific” and “deplorable.”
