U.S. Border Patrol agents said they were attacked with rocks while providing assistance to a pregnant near the Progreso Port of Entry in Texas.
It happened as Border Patrol agents saw a group of illegal immigrants trying to use a tree to climb up the Progreso Port of Entry into the United States.
When they tried to give the woman medical attention, one of the other people in the group began throwing rocks at the Border Patrol agents.
The agents were able to move the pregnant woman to a safe location. The assailants then fled back to Mexico, the agency said.
The woman still needs to be cleared by medical staff, and she will be processed by immigration officials, officials noted.
Between Oct. 1, 2107, and June 30, 2018, the Rio Grande Valley Sector of the Border Patrol rescued 1157 people, an increase of 53 percent when compared to last year, officials noted.
Earlier this week, the agency said that agents near Edinburg, Texas, rescued a 3-year-old separated from her mother by smugglers who was abandoned in the Rio Grande river.
When agents responded, they saw a female claiming that her daughter was missing.
A National Guard helicopter and other units were mobilized to search for the child. They found the child walking on a river road and checked her for injuries before reuniting her with her mother.
