Mexico City: The Mexican government says one of its citizens was shot by US Border Patrol agents on the border with Texas.
Mexico says it condemns what it calls disproportionate use of force.
The Border Patrol said Saturday that agents had opened fire along the Rio Grande border after being pelted by rocks and having a gunman point a weapon in their direction from the Mexican side of the river.
The agency said it did not know if anyone else was hurt but said the Mexican government had been notified and was responding to the area. The FBI also was investigating.
The Mexican Foreign Ministry on Monday did not identify the victim, or give details of the incident, but said it told the US that the use of lethal force was unacceptable.
