MCALLEN, TEXAS (AP) -- A Border Patrol spokesman says agents patrolling the Rio Grande in south Texas fired rounds into Mexico after their boat was "bombarded" by objects from the Mexican side.
Jose Trevino said agents feared for their safety Monday morning when the objects hit the boat in the river that divides the U.S. and Mexico.
The incident happened about 8 a.m. near the border city of McAllen, about 250 miles south of San Antonio.
Trevino said no injuries were reported, and he had no information on the type of objects that hit the boat.
Trevino also said he didn't know how many agents were on the boat or how many rounds they fired into Mexico.
The incident is under investigation.
