U.S. authorities informed some migrants of plans to deport them to Libya, a country they are not from and that has a history of human rights violations, attorneys said.

A court says the Trump administration can’t deport people to Libya without giving them proper notice, presenting yet another hurdle for the plans.

A federal judge has placed a hold on the U.S. government’s plans to deport a number of immigrants to Libya, following allegations from immigrants, their families and their lawyers that Immigration and Customs Enforcement (ICE) officials told them they would soon be sent to that country.
