Mexico Furious After US Border Guard Kills Boy, 15

Mexico has demanded the US investigate the shooting of a 15-year-old Mexico boy by Border Patrol agents under a bridge linking El Paso and Ciudad Juarez. The FBI says the boy was part of a group of suspected illegal immigrants who were throwing rocks at an agent. Witnesses and Mexican police say the boy was shot on the Mexican side of the border, the El Paso Times reports.

"Using firearms to respond to an attack with rocks is a disproportionate use of force, particularly coming from officials that are specially trained ," Mexico's foreign ministry said in a statement. The chief of the union representing Border Patrol agents says a rock attack is "a deadly force encounter, one that justifies the use of deadly force." The agent responsible has been placed on leave.
