The deaths in Mexico came just hours after the United Nations High Commissioner for Refugees urged the Biden administration not to adopt a proposed anti-asylum rule that would deny claims made by refugees who lack “documents sufficient for lawful admission.” In a statement, the U.N. refugee agency said the regulation would restrict the fundamental human right to seek asylum, adding, ”UNHCR is particularly concerned that … this would lead to cases of refoulement — the forced return of people to situations where their lives and safety would be at risk — which is prohibited under international law.”
