hooting in Tucson, Arizona, leaves 10 people wounded,

Ten people, including a suspect, were wounded in a mass shooting that erupted early on Sunday in a busy commercial district near downtown Tucson, Arizona.



Police officers on routine foot patrol rushed toward the sound of gunfire at about 2 a.m. local time and encountered a suspect, to whom they gave "repeated commands" and then shot.



The officers rendered first-aid to the suspected gunman, and he was transported to a local hospital with life-threatening wounds.



Nine other people were wounded, apparently before police arrived on the scene, and they were taken to hospitals in critical condition, many of them with gunshots to their extremities.



All the victims were adults, and no police officers were injured.



Police offered no official details on what may have precipitated the gun violence, which occurred amid large numbers of people out on the street for the night.
