The Mexican government says it regrets a ruling by the US Supreme Court that bars the family of a Mexican boy who was killed in 2010 from suing the US border patrol agent who shot him. The boy, Sergio Hernández, was shot dead on Mexican soil by US border patrol agent Jesús Mesa, who was on the US side of the border. The court ruled that the parents could not use US courts to sue Mr Mesa. The Mexican government says it is concerned it could set a precedent. The incident happened on the border between El Paso, Texas, and Juárez, Mexico. Agent Mesa was on a bicycle patrol on the US side of the border and was reportedly alerted to the presence of people smugglers.

Sergio Hernández, 15, was with a group of youths in the dry bed of the Rio Grande when Agent Mesa approached.
