Costa Rica is the second Central American nation to accept migrants from distant countries as the Trump administration ramps up deportation flights.

“Panama cannot end up becoming a black hole for deported migrants,” said Juan Pappier, deputy director of Human Rights Watch in the Americas. “Migrants have the right to communicate with their families, to seek lawyers and Panama must guarantee transparency about the situation in which they find themselves.”

Panama received three U.S. deportation flights last week with migrants from China, Uzbekistan, Pakistan, Afghanistan, and other countries.

Officials in Costa Rica and Panama are confiscating migrants' passports and cellphones, denying them access to legal services and moving them between remote outposts as they wrestle with the logistics of a suddenly reversed migration flow.

Panama and Costa Rica are among a number of Latin American nations that have agreed to cooperate with U.S. President Donald Trump as he ramps up his deportation machine and restricts access to asylum in the U.
