'A new normal': Migrants huddle in open-air camps on US border

Hundreds of migrants who cross into the United States each day are being herded into open-air camps, where they have no access to food or water, and some are left to sleep on the open ground in a desert riddled with scorpions and snakes, activists say. "I don't want my son to suffer like I did. I chose to do everything I could to come here," says Ecuador national Carla Morocho.
