Why thousands of migrants, many from Haiti, are stuck at Texas-Mexico border

A mounting crisis is unfolding at the U.S.-Mexico border where thousands of migrants, many from Haiti, have trekked across dozens of countries, facing blistering heat and other dangers to seek refuge in the United States.

But entering the land of the free has proved difficult after migrants waded across the border. They were met by Border Patrol agents and deportation efforts.

All eyes are on the small town of Del Rio, Texas, where at one point more than 14,000 migrants, the majority from Haiti, were sheltering under a bridge.

One of the migrants, Jean Baptiste Wilvens, told ABC News he crossed 11 countries to get to the U.S. after he and his family had been living in Chile for the last four years.
