A federal judge on Wednesday warned a Trump administration plan to send undocumented immigrants to Libya would violate a court order issued in March. Lawyers for immigrants from Laos, Vietnam and the Philippines believe a North Africa-bound deportation flight could take off as early as this week. But Libya’s two rival governments have denied any such agreement with the U.S., calling the potential move a violation of the country’s sovereignty. Libya has a track record of gross human rights violation in its treatment of refugees and immigrants; the U.N. has reported “widespread practices of arbitrary detention, torture, rape and slavery.”
