Mexico's ambassador to the United States says it appears a teenager who threw rocks at Border Patrol agents in the Arizona city of Nogales died from a gunshot wound.

The death of 17-year-old Ramses Barron Torres has been in dispute since a Mexican official said the teen died Wednesday after he fell from a border fence and hit his head on a rock.

But state police in Sonora, across the border from Arizona, said companions of the Barron Torres claim he was shot by a U.S. Border Patrol agent after the youths had illegally crossed the border.

Speaking at a conference Thursday in Mexico City, ambassador Arturo Sarukhan says it now appears "to be clear that the death was the result of a gunshot wound."
