Several Mexican nationals armed with slingshots fired small rocks at CBP

Several Mexican nationals armed with slingshots fired small rocks at U.S. Customs and Border Protection agents who were patrolling in San Luis, Ariz., Tuesday.

The agents, who were from the Yuma sector, were working about three miles east of the San Luis port of entry when the assailants began shooting rocks at the agents from the Mexican side of the international border.

Able to stay out of the slingshotters' range, agents stayed in visual contact with their assailants and contacted Mexican authorities.

Once on scene, Mexican authorities dispersed the group but made no apprehensions. None of the agents or their vehicles sustained any damage.

From Oct. 1 through June 30, agents have faced a 43 percent increase in violence, with 174 reported incidents compared to 122 incidents during the same period last year.
