TUCSON, Ariz. — Mexican law enforcement on Thursday crossed into Arizona by helicopter and fired two shots at U.S. border agents, a border patrol union leader says.
A Mexican law enforcement chopper crossed about 100 yards north into the Arizona desert, the U.S. Border Patrol said in a statement. The helicopter then fired two shots on the Tohono O’Odham Indian Nation, which sits on the border. Border patrol union leaders say the Mexicans fired at agents but that none of them were hurt.
