Shots fired as U.S. Border Patrol agents were tending to injured boy near San Diego crossing, officials say

Shots were fired near U.S. Border Patrol agents and first responders as they were helping an injured 4-year-old boy near the U.S.-Mexico border, federal officials said Friday. The incident happened about a half-mile east of the San Ysidro border crossing in San Diego on Monday night, according to the U.S. Customs and Border Protection agency.

The unidentified boy was dropped from a "primary border barrier" by someone entering the U.S. illegally, according to a Customs and Border Protection statement.

As Border Patrol agents helped the boy, shots rang out, the agency said.
