United Nations officials are pushing for many of the Central Americans fleeing to the U.S. to be treated as refugees displaced by armed conflict, a designation meant to increase pressure on the United States and Mexico to accept tens of thousands of people currently ineligible for asylum.

Officials with the U.N. High Commissioner for Refugees say they hope to see movement toward a regional agreement on that status Thursday when migration and interior department representatives from the U.S., Mexico, and Central America meet in Nicaragua. The group will discuss updating a 30-year-old declaration regarding the obligations nations have to aid refugees.
