Mexican law enforcement has fired two shots from a helicopter into the Arizona desert after the aircraft crossed the U.S. border.
The U.S. Border Patrol said in a statement that a Mexican law enforcement chopper crossed about 100 yards north into the Arizona desert on Thursday morning.
The helicopter then fired two shots on the Tohono O'Odham Indian Nation, which sits on the border.
There were no injuries or damage to property. The border patrol has declined to say whether any American agents were near the shooting.
The agency has also declined to say what branch of law enforcement the Mexican helicopter was from.
Sebastian Galvan, a spokesman for the Mexican Consulate in Tucson, said the office was gathering information but did not have any details yet.
