The head of the United Nations agency for refugees is warning countries not to abandon the post-World War II framework for humanitarian migration, including the 1951 Refugee Convention. Filippo Grandi made the remarks Monday as some European nations — and the Trump administration — seek to limit the right of refugees to request asylum.

Filippo Grandi: “I’m worried that the current debate in Europe, for example, and some current deportation practices, such as in the United States, address real challenges in manners not consistent with international law.”
