The police said none of the children was injured in the attack. 

"From the officers who responded to the shooting to the investigators still on scene, we are all left incredibly shaken," Vince Niski, Colorado Springs police chief, said . 

"This is something you hope never happens in your own community."

Colorado Springs mayor John Suthers called the shooting a "senseless act of violence" and expressed sympathies with victims, their families and the first responders. 

In recent months, mass shootings have been on a rise in the US, and US President Joe Biden has earlier described such incidents as an "epidemic" and an "international embarrassment."
