Mexican forces chase away U.S. authorities on border

CIUDAD JUÁREZ, Mexico - Pointing their rifles, Mexican security forces chased away U.S. authorities investigating the shooting of a 15-year-old Mexican by a U.S. Border Patrol agent on the banks of the Rio Grande, the FBI and witnesses told The Associated Press yesterday.

The killing of a Mexican by U.S. authorities, the second in less than two weeks, has exposed the distrust between the two countries that lies just below the surface, and has enraged Mexicans who see the death of the boy on Mexican soil as an act of murder.

Mexico's government says the number of Mexicans injured by U.S. immigration authorities has increased this year.

Shortly after the boy was shot, Mexican soldiers arrived at the scene and pointed their guns at the Border Patrol agents across the riverbank while bystanders screamed insults and hurled rocks and firecrackers, FBI spokeswoman Andrea Simmons said. She said the agents were forced to withdraw.

"It pretty quickly got very intense over on the Mexican side," she said, adding that FBI agents showed up later and resumed the investigation, even as Mexican authorities pointed guns at them from across the river.

A relative of the dead boy who had been playing with him told the AP that the Mexicans, whom he described as federal police, not soldiers, pointed their guns only when the Americans waded into the mud in an apparent attempt to cross into Mexico.

The Mexican authorities accused the Americans of trying to recover evidence from Mexican soil and threatened to kill them if they crossed the border, prompting both sides to draw their guns, said the 16-year-old boy who asked not to be further identified for fear of reprisal.

The confrontation occurred Monday night over the body of Sergio Adrian Hernandez Huereka, who died of his wounds beside the column of a railroad bridge connecting Ciudad Juárez, Mexico, and El Paso, Texas. Each government has made veiled accusations suggesting misconduct on the part of the other's law enforcement agents.
