The incident happened about 5 p.m. Friday while the aircraft was patrolling the Rio Grande near the far northwest corner of the border city of Laredo.
Webb County Sheriff Martin Cuellar (KWAY’-yahr) tells the Laredo Morning Times ( http://bit.ly/1Kg0ji2 ) that out of five shots believed to have been fired at the helicopter, two are confirmed to have hit their target.
Border Patrol spokeswoman Sara Melendez says no one aboard the aircraft was injured. The helicopter landed safely.
There was no immediate word on whether the gunfire came from the Mexican side of the river or the U.S. side.
