Gleyders Durant, 27, a migrant from Venezuela, peeled off bandages on his right foot to reveal several wounds. He said that as he crossed the river on Friday and stepped onto U.S. soil — his 3-year-old son on his shoulders and his wife following them — he felt a sharp pain. Blood gushed through one of his tennis shoes. “That’s when I realized that I had stepped on a stretch of wire hidden under dark waters,” he said. Panicked, he extended his arms and carried his wife over it. “It was hidden, under the water.”
