Two U.S. Border Patrol agents wounded last week near Nogales, Ariz., were shot by assailants dressed in black commando-type clothing in what law-enforcement authorities say was a planned ambush by drug smugglers a mile north of the U.S.-Mexico border.
More than 50 rounds were fired at the agents after they spotted suspected drug smugglers in a canyon east of Nogales, authorities said. Although most of the suspected smugglers fled, one of the men opened fire and the other used a hand-held radio to point out the agents' location to at least two other shooters hidden nearby, they said.
The agents, who were backtracking a previous marijuana load on foot, were shot in the leg with high-powered weapons. Both agents were in uniform at the time of the shooting. Authorities said the gunmen withdrew from the canyon using military-style cover and concealment tactics to escape back into Mexico. No one was arrested.
Santa Cruz County Sheriff Tony Estrada, whose jurisdiction includes the Nogales area, said at least four shooters were involved. He said investigators found commando clothing, food, water and other "sophisticated equipment" at the site.
"The fact they would shoot at law-enforcement officers deeply concerns us. They have always protected their drug loads, usually against other drug gangs, but they have bumped it up one more level," Sheriff Estrada said. "It's clear they intended to intimidate the agents in an ambush, but whether they wanted to kill them is not known....

A Border Patrol report on the incident said the agents observed a dozen men dressed in dark clothing sitting under a tree and that as they approached from different directions, they identified themselves in Spanish and ordered the men to stay seated.
The report said all but two of the men fled, but one man "put something up to his mouth, as if talking on a radio," pointing at the two agents as the second man began firing. It said the agents returned fire, moved to cover and then began "receiving gunfire from another direction." After the first agent was hit, the second was wounded as he tried to reach his partner, the report said.
Two Black Hawk helicopters responded, but the gunmen had fled. Authorities later found 500 pounds of marijuana.
