The U.S. Border Patrol says Mexican law enforcement crossed into Arizona by helicopter on Thursday and fired two shots at U.S. border agents. According to the US agency, the Mexican law enforcement copter crossed 100 yards north into the Arizona desert, then then fired two shots on Tohono O’Odham Indian Nation reservation. From Reuters:

"A Mexican law enforcement helicopter crossed approximately 100 yards (100 meters) north into Arizona nearly 8 miles (13 km) southwest of the Village of San Miguel," U.S. border officials in Tucson said. "The incident is currently under investigation." A spokesman for Mexico's federal prosecutor said the incident had "apparently involved an army helicopter" but declined to elaborate. Mexican army officials could not immediately be reached for comment. Shawn Moran, vice president of the National Border Patrol Council, which represents some 17,000 border agents, said the shots were fired at a Border Patrol vehicle.

This isn't the first time Mexico's army has crossed over the international boundary. AP:

In January, U.S. border agents confronted two heavily armed Mexican soldiers who crossed 50 yards inside Arizona, the Los Angeles Times reported. A standoff ensued, but nobody was hurt. In 2011, more than 30 uniformed Mexican soldiers in military vehicles crossed the Rio Grande without authorization in an incident that was believed to be inadvertent.
