Sparks, Nevada: A student at a Nevada middle school opened fire on campus, killing a staff member who was trying to protect other children, police said on Monday.
The suspected gunman was also dead, and authorities say no shots were fired by law enforcement.
Two other students were critically injured in the violence that erupted around 7.15 a.m. local time, shortly before classes began on Monday. One is out of surgery and the other is doing well, according to police.
Police said between 150 and 200 officers responded to the shooting.
Students from the middle school and next door elementary school were evacuated to the nearby high school, and classes were cancelled.
