Shots fire during Rio Grande drug bust

SAN ANTONIO (AP) - The U.S. Border Patrol says agents fired gunshots into Mexico after coming under attack while making a drug bust along the Rio Grande.

Border Patrol spokeswoman Rosalinda Huey said Monday that no agents were injured during a "fire fight" in Mission over the weekend.  She's not saying whether anyone in Mexico was hit by Border Patrol gunfire, citing the ongoing investigation.  Huey says Border Patrol agents were seizing a half-ton of marijuana Saturday when the shootout began. Officials say a truck pulled up on the U.S. side of the border, then someone opened fire on the agents from the Mexican side.

In June, a Border Patrol agent fatally shot a 15-year-old Mexican boy after authorities say a group trying to illegally enter Texas threw rocks at officers near downtown El Paso.
