Shocking new video shows hundreds of migrants crossing the Rio Grande near Eagle Pass and struggling to illegally enter the United States, as the southern border continues to near a breaking point.

Eagle Pass, Texas, has encountered over 3,000 undocumented migrants in recent days. It's one of many southern cities overwhelmed by the flood of migrants at the border. 

In El Paso, border agents are already at their limits with just over 4,000 migrants in custody in the city.
