Faced with imminent drop in temperatures during the winter, Chicago, New York and other U.S. cities have been under pressure to fix shelter for the thousands of migrants camped out in the open on their streets.
Chicago, the nation's third-largest city, announced an agreement with religious leaders to shelter 400 people waiting for asylum in churches. But another 1,000 migrants continue to live at O'Hare International Airport and police stations.
Construction of a migrant camp in Illinois was halted in early December after a report found high levels of mercury, lead and other toxic elements at the site.
In New York, the situation has rapidly worsened, with 120,000 asylum-seekers arriving in the city over the past year. The mayor has launched a program dedicated to providing migrants with free plane tickets to other destinations as a way to relieve overcrowding at shelters.
