An American consular official was shot in Guadalajara, Mexico's second largest city in the restive western state of Jalisco. But the official is now in stable condition, Mexican authorities said today. <br/><br/>Mexican federal and state officials are investigating the incident, which occurred on Friday evening, the attorney general's office said in a statement. <br/><br/>The US Embassy could not immediately be reached for comment. Jalisco is one of the engines of the Mexican economy, but the state's southern border turned into a battleground between the Jalisco New Generation Cartel (JNG) and the Michoacan-based Knights Templar. In May, 2015 JNG gunmen shot down an army helicopter in southwestern Jalisco, claiming the lives of six military personnel.
