A mass shooting in downtown Tucson, Arizona, left nine people wounded and the alleged gunman with life-threatening injuries, prompting local concern over ongoing gun violence in the city and renewed political debate over gun control. The Democratic mayor has since called for tighter gun laws, while residents say the incident reflects a broader pattern of late-night violence that has spiralled out of control in the area.

The shooting broke out at around 2am near Empire Pizza, at the junction of East Congress Street and Sixth Avenue, a busy nightlife district popular with people leaving bars and restaurants. Police believe the violence stemmed from a confrontation between two groups whose members knew each other, with several bystanders caught in the crossfire as the situation escalated.
