On Friday, the United States said a border camp between the cities of Del Rio in Texas and Ciudad Acuna in Mexico had been emptied of thousands of migrants, most of them Haitian. Some were flown out, while others stay in the United States for now. Thousands have fanned out across northern Mexico in recent weeks, spurring concern among officials that mass crossings such as those seen in Ciudad Acuna could happen elsewhere. In the city of Monterrey a few hundred kilometers to the southeast, about 2,000 Haitians have gathered, tallies by migrant shelters show. Roberson, a 42-year-old Haitian solderer who had traveled from Brazil, said he was fed up with paying money to "guides" and had just submitted an application for asylum in Mexico.
