Gunmen killed 15 people in a mass shooting at a drug rehabilitation center in the northern border state of Chihuahua in what was apparently a feud between drug gangs, Mexican authorities said Wednesday. The Chihuahua state prosecutor's office said "initial investigations prove that the attack was related to drug distribution and the feud between the Mexicles and Aztecas gangs." Prosecutors said at least seven other people were wounded in the attack in the state capital, also called Chihuahua. Drug cartels have been known to use rehab centers to recruit addicts, and rival gangs sometimes assault the centers. In a statement Wednesday, the state prosecutor's office said the officers were killed Tuesday near the town of Tecalcingo.
