Mexico protests shooting death of teen at Texas border

For the second time in less than two weeks, the death of a Mexican national at the hands of U.S. border agents is outraging Mexicans and testing relations between the two countries.

The Mexican government Wednesday vigorously protested the shooting this week of a 15-year-old boy at Mexico's border with Texas.

The boy, Sergio Hernandez Guereca, died of a wound to the face. U.S. officials say he died after a Border Patrol agent opened fire Monday night on a group of Mexicans throwing rocks at the agent, who was attempting to arrest suspected illegal immigrants.
