“A shootout near the U.S.-Mexico border between rival groups with ties to organized crime left 21 people dead Thursday, Mexican police officials said.
Two groups authorities believe were involved in drug and human trafficking clashed in a deserted area about 12 miles south of the border, Sonora State Police spokesman Jose Larrinaga Talamantes told CNN.
Investigators recovered eight bullet-riddled vehicles and seven weapons from the area, about 20 miles south of Nogales, Arizona, he said. The cause of the shootout is unknown, he said, but authorities hope to get more information from suspects in custody.”
