Migrant children with numbers on arms wait to cross border

08:13

NBC News' Cal Perry reports on children waiting to cross into the US from Juarez, Mexico. Editor’s Note: According to the Mexican Embassy, the people drawing numbers on the arms of migrants are volunteers and members of an NGO—not Mexican officials as we first reported. They say the action was taken to ensure that people kept their place in line for entry into the U.S. after migrants were moved off the Paso del Norte bridge.
